Netflix’s Tick, Tick...Boom! is a true story that adapts the semi-autobiographical musical by Jonathan Larson, with many aspects being accurate to his real life and future success with Rent. The movie, directed by Hamilton’s Lin-Manuel Miranda, follows Jonathan Larson (Andrew Garfield) as he reaches his 30th birthday, feeling the pressure of time running too quickly without a produced musical. While feeling the rejection of his unsold Superbia musical, Jon’s creative ambition also takes a toll on his relationships with his girlfriend Susan (Alexandra Shipp) and best friend Michael (Robin de Jesús).

Tick, Tick...Boom! is based on a real-life rock monologue originally written and performed by Jonathan Larson in 1992, telling the story of his creative struggle in 1990, six years before his musical Rent could become one of the most influential works in Broadway history. Following Larson’s unexpected death in 1996, the rock monologue was turned into its own musical, with some of Tick, Tick... Boom!'s songs coming from past works like Superbia. Premiering Off-Broadway in 2001, Tick, Tick… Boom! developed a significant reputation for its poignancy, detailing Larson’s conflicted journey of artistry before writing Rent, a musical he would sadly never get to see on the Broadway stage.

Considering Netflix’s Tick, Tick...Boom!'s true story is an adaptation of the semi-autobiographical musical and not a specific biography of Larson, there are several changes or omitted important moments from his real life. As said at the beginning of the movie, the events portrayed in Tick, Tick...Boom! are a true story, aside from the moments that Jon made up. While painting a portrait of who Jonathan Larson was in the year 1990, the positively-reviewed Tick, Tick... Boom! includes some of the most fantastical true aspects of his artistry, though leaves out many details about his alternate work at the time, tragic death, and which aspects of Rent were inspired by his real life.

Tick, Tick...Boom! Is Based On A True Story

Netflix tick tick boom ending explained Jonathan Larson death broadway legacy

Lin-Manuel Miranda's Tick, Tick... Boom! is a true story about Jonathan Larson's life in the year 1990 as his ambition races time, with the composer desperately working to become successful before his 30th birthday. Much of   Tick, Tick... Boom!'s true story is derived from Larson's semi-autobiographical 1992 musical of the same name, but Miranda's biopic also integrates aspects of Larson's life during this time based on research that included interviews with his family, friends, and colleagues. Extending the portrait of Jonathan Larson's life not included in Tick, Tick...Boom!'s stage musical, Encanto songwriter Lin-Manuel Miranda included a documentary-style scene at the end of the movie to summarize the true story of the composer's career contributions, acclaim and reception, future accomplishments, and the circumstances of Larson's sudden death in 1996.

Jonathan Larson’s True Friendship With Stephen Sondheim

Although it seems incredible that a young artist with Stephen Sondheim routinely reading his work would have trouble getting musicals produced, Tick, Tick… Boom!’s working friendship between Jon and one of the greatest composers of all time is true. When Larson was in college, he came into contact with Sondheim, who famously wrote iconic musicals like West Side Story, Into The Woods, Sunday in the Park with George, and Sweeney Todd: The Demon Barber of Fleet Street. After beginning a rapport with his idol, Jon began submitting his work to Sondheim for review, who would often write recommendation letters to producers on the true Tick, Tick... Boom creator’s behalf.

Throughout Tick, Tick... Boom!, Andrew Garfield's character is constantly comparing himself to Sondheim’s timeline of achievements, proving just how much he idolizes the artist. In an important moment, Stephen Sondheim (Bradley Whitford) shows up to see the workshop for Superbia, a show Sondheim really did give Larson notes on. Tick, Tick… Boom! is filled with homages and references to Sondheim, including the song “Sunday” - which features a plethora of iconic Broadway actors in the movie - that Larson composed as a tribute to Sondheim’s Sunday in the Park with George. The end of Tick, Tick...Boom! also features Jon getting a call from Sondheim, telling him Superbia is first-rate and has a future, just like Jon. Director Lin-Manuel Miranda told The New Yorker that he originally wrote Sondheim’s voicemail to say “I have a feeling you’re going to have a very bright future,” but Sondheim told him it sounded too cliché. In a poetic appreciation of his once mentee, Sondheim decided to change the final voicemail in Tick, Tick... Boom!'s true story to commending Jon’s play and future as first-rate, with Sondheim even cameoing to voice himself in the scene.

Susan & Michael Aren’t Real People

Tick Tick Boom every song ranked worst to best

Tick, Tick... Boom!’s stage musical only features three characters: Jonathan, Susan, and Michael. In the movie, plenty of other characters are introduced to bring Larson’s 30th year, workshops of Superbia, Moondance Diner job, and Bohemian lifestyle to the screen. Aside from Jonathan and Stephen Sondheim, nearly every character in Tick, Tick… Boom!'s true story is partially fictional, being based on real figures in Larson’s life. As two of the other main characters in Tick, Tick… Boom!, it’s surprising that Susan, Jonathan’s girlfriend, and Michael, his best friend, aren’t real people. Instead, Susan, Jon’s dancer girlfriend in Tick, Tick… Boom!, is partially based on a dancer that Larson dated for four years while he was writing and workshopping Superbia - a character that would more autobiographically be worked into Rent. Michael, in turn, is inspired by Larson’s real-life childhood friend Matt O’Grady, who truly was diagnosed as HIV-positive during this time.

Lin-Manuel Miranda revealed that Michael’s real-life counterpart is alive and healthy today, saying he’s practically a champion swimmer. Tick, Tick… Boom!’s director also said he contacted the real-life inspiration for Susan, who is still a dancer today. Susan’s true Tick, Tick... Boom! inspiration had more issues with how Larson wrote about her, saying she “never wanted to move to an ashram,” and that, as a dancer, the concept of time running out was much more important to her than Tick, Tick… Boom!'s ending portrayed. Matt and Susan’s inspiration remember the events of his time slightly differently than Larson portrayed, but, at the end of the day, Tick, Tick… Boom!'s truth almost all comes from Larson’s recollection of this time, meaning he can’t be 100 percent reliable as the narrator.

Tick, Tick...Boom! Leaves Out A Few Of Larson's Musical Works

The true story of Tick, Tick… Boom! touches on some of Larson’s most important real-life works of the time, particularly his unproduced musical Superbia, his titular musical monologue, and the early foundations of Rent. While Jon and Michael briefly talk about how Larson could easily get paid for writing jingles at Michael’s advertising firm, the movie’s protagonist brushes it off. In real life, Tick, Tick, Boom!'s songwriting protagonist was truly adamantly opposed to such work when it was for companies whose politics he disagreed with or when he thought he was going up against writers who were truly committed to working in the jingle industry, but he did notably write a few, including a rejected CNN jingle - which the movie includes as an Easter egg.

In relation to Larson’s more significant works at this time, Tick, Tick… Boom!'s true story leaves out a 1992 musical, Sacred Cow, that he collaborated on with fellow composers. The musical was pitched to TV networks as a weekly anthology series tackling different Biblical and mythological stories featuring ‘90s celebrity cameos. The project was shelved due to scheduling conflicts with the composers, but the original demo recording finally resurfaced in 2013 (via Playbill). Larson’s other musical compositions omitted from Netflix's November 2021 movie are his contributions to J.P. Morgan Saves The Nation; music for Sesame Street; compositions for the cassettes of children’s books like The Land Before Time; a musical titled Mowgli; compositions for a Rolling Stone magazine publisher; and four songs for the kids’ music video Away We Go! from 1996.

How Much Of Rent Was Based On Larson’s Real Life

The lead cast of Rent

Regarded as Larson’s most influential work, Rent featured several autobiographical elements, fulfilling the advice he gets in the true story of Tick, Tick… Boom! to write about what he knows. In real life, Larson and his Bohemian-style roommate, Jonathan Burkhart, lived in a rundown apartment with an illegal wood-burning stove, just like Rent’s main characters, even down to the key that had to be thrown down outside. As already touched on with the real-life inspiration for Susan in Tick, Tick...Boom!, Larson’s four-year-long girlfriend inspired the character of Maureen (originated by Frozen's Idina Menzel on Broadway) in Rent. Just like in the musical, Larson’s dancer girlfriend would occasionally leave him for other men, though finally left him for another woman. One aspect of Tick, Tick… Boom!'s true story that most clearly overlaps with Rent’s themes and Larson’s real experience is the AIDS epidemic, which had begun to affect many of his closest friends. In the movie, one of Jon’s coworkers is hospitalized for it, while his best friend Michael gives him the news that he’s HIV-positive in an emotional conversation about time running out.

According to Playbill, Rent’s main character Mark Cohen is partially inspired by Larson’s friends Jonathan Burkhart, a cinematographer who “sold out” for money over the struggling artist lifestyle, and Eddie Rosenstein, a documentarian who influenced Mark’s documentarian aspect of Rent. Roger, on the other hand, is partially influenced by Tick, Tick..Boom!'s stage protagonist, most clearly in the motif of artistry and trying to produce the perfect song before his time runs out. While most of the characters were still fictional and based on the 1988 musical La Boheme, Larson’s real experiences were deeply engraved in Rent, though in a more fictional manner than Tick, Tick...Boom!'s true story.

Jonathan Larson’s Sudden Death Explained

Aside from being the genius composer behind Rent, Larson was notable for the tragic circumstances behind his death. On the morning of Rent’s Off-Broadway preview premiere in January 1996, the protagonist of Tick, Tick...Boom!'s true story passed away from an aortic dissection. Larson had been afflicted with flu-like symptoms during the technical period of Rent’s preparations, with the composer eventually facing severe chest pains, dizziness, and shortness of breath for the last few days before his death. He went to the hospital for the symptoms, but x-rays didn’t show an aortic aneurysm, leading them to misdiagnose it as flu or stress. After the Andrew Garfield movie's real-life creator passed, doctors revealed that had his condition been accurately diagnosed and treated with surgery, he may have lived. Professionals have also come to believe Larson’s aortic dissection was caused by undiagnosed Marfan syndrome, a rare genetic disorder that can lead to severe complications with the heart and aorta. Tick, Tick… Boom!’s true creator passed away at only 35 years old, tragically never being able to see the success of his influential musical Rent, or the lasting legacy of the titular monologue he performed.

Is Matt O'Grady Still Alive?

Jonathan Larson's best friend in the true story of Tick, Tick...Boom! is Michael, who is based on Jon's real-life friend Matt O'Grady. The real Matt O'Grady provided a significant amount of information to Lin-Manuel Miranda about Jonathan Larson and his own role in the composer's life at this time. After informing Jonathan that he's HIV-positive, Michael survives to the end of Netflix's 2021 Tick, Tick...Boom! movie and outlives the protagonist, much like his real-life counterpart. Matt O'Grady is still alive today after being diagnosed as HIV positive in 1986, which, as Tick, Tick...Boom's true story depicts, he recalled being a "death sentence" at the time (via 27east.com). Miranda has also noted that O'Grady is "healthier than any of us" as a champion swimmer, confirming the true Tick, Tick...Boom! inspiration is still alive and well today.
