Here's where to watch Insidious: The Last Key online, and whether the Blumhouse horror sequel is available on Netflix, Hulu or Prime. While James Wan became a new horror icon following the unexpected success of his 2004 directorial debut Saw, he struggled with his immediate follow-ups. He reteamed with Saw collaborator Leigh Whannell for Dead Silence, an evil doll movie that was a nightmarish production that was also a box-office dud. Wan then tried a vigilante action thriller called Death Sentence - which was based on a sequel novel to Death Wish - starring Kevin Bacon.
While Death Sentence is considered one of the helmer's most underrated works, it was also a financial letdown. Wan and Whannell decided to go back to their low-budget roots and teamed with Blumhouse to make the first Insidious movie. This found a family dealing with a very unusual haunting, and the movie's great cast and expert use of tension and jump scares made it a huge success. Wan returned to direct Insidious: Chapter 2, which acted as a direct sequel to the events of the original, before Whannell made his directing debut with Insidious: Chapter 3, which took the series in a new direction.
Director Adam Robitel was handed the keys - quite literally - to 2018's Insidious: The Last Key. This fourth entry made Lin Shaye's fan-favorite Elise the lead, though due to the events of the original, The Last Key is actually set before it. The movie received lukewarm critical reviews overall, though Shaye's emotional performance and the focus on Elise's backstory was met with praise. Unfortunately, the sequel is currently unavailable for stream from services like Netflix, Hulu or Amazon Prime.
That said, Insidious: The Last Key is easily available to purchase or rent from most major platforms, including iTunes, Google Play, Red Box, Spectrum, and others. Another element of The Last Key that was well-received was the design and concept behind the KeyFace demon, who quite literally has keys for fingers. He made a fitting final opponent for Elise to face too, given his ties to her past.
It appears Insidious: The Last Key might be the end of Shaye's Elise in the series too. The next entry Insidious 5 will be star and be directed by Patrick Wilson, who played Josh Lambert in the first two entries, and the story will deal with his son Dalton (Ty Simpkins) heading off to college. While it's always possible Elise could return either via a flashback or as a spirit, the future of the franchise probably won't feature the character in a major way.
