Although she’s best known for her portrayal of Dr. Marlena Evans on “Days of our Lives,” actress Deidre Hall has also played memorable roles in numerous other television shows, most notably “Emergency!” and “Columbo.”

In celebration of Hall’s time on both shows, COZI TV will air a four-hour mini-marathon of episodes featuring Hall in the aforementioned series on Saturday, May 18, starting at 8:00 a.m. ET/7:00 a.m. CT.

The marathon, titled “Day of our Deidre,” begins with two episodes from the second season of “Emergency!” (“Show Biz” and “Saddled”), where Hall portrayed Nurse Sally Lewis. It will be followed by a two-hour episode from the ninth season of “Columbo” (“Columbo Cries Wolf”) at 10:00 a.m. ET. In that episode, Hall appears as Dian Hunter.

“Before becoming a daytime TV icon, Deidre Hall honed her craft on some of TV’s most beloved series. Now, join COZI TV for a day of her early memorable roles,” an announcer says in a recent promo published by the network on X (formerly Twitter) touting the upcoming Hall-centric marathon.

In addition to “Columbo” and “Emergency!” COZI TV features a robust lineup of programming, intermixing the classics with more modern fare such as “3rd Rock from the Sun,” “Frasier,” “Bones,” “Heartland,” “Highway to Heaven,” “Las Vegas,” “Roseanne,” “The Nanny,” “The Munsters,” “Monk” and “Little House on the Prairie,” among others.
