Ashley Park is Kimber
Ashley Park plays Kimber, a young actor in Oliver’s play. While we don’t know a lot about Kimber yet, Park told Entertainment Tonight at the red carpet premiere for Joy Ride in June, that she can’t say a lot about her character yet, but that “if people know my roots of where I came from, they’ll be happy [to see similarities in Kimber] in terms of how I started in this business.” Though most people likely recognize Park from her role in the Netflix series Emily in Paris, the actor got her start on broadway, performing in shows like Mamma Mia!, Mean Girls, and Sunday in the Park With George.
Jesse Williams is Tobert
Jesse Williams plays Tobert, a documentary director hired by Glenroy to film his Broadway debut. Based on one of the latest trailers for this season, it looks like Tobert could be a love interest for Mabel as they work together to solve Glenroy’s murder, but it’s probably too soon to trust him completely.
Williams is well-known for his roles in Grey’s Anatomy and The Cabin in the Woods, but Only Murders in the Building season 3 isn’t the first time the actor has taken a broadway-adjacent role. In 2022, the actor made his broadway debut as Darren Lemming in the revival of Take Me Out and earned a Tony nomination for his time in the role.
Tina Fey is Cinda Canning
Tina Fey is returning this season as podcast juggernaut Cinda Canning. Last season, Cinda was framed for Bunny’s murder by her assistant Poppy a.k.a Becky Butler, the not-so-dead murder victim of Cinda’s most popular podcast. Not only does she learn that her assistant is a cold-blooded murderer, but that the story she built her entire career on is a lie. It will be interesting to see if Cinda has been able to maintain her credibility despite this revelation, or if she’ll need Glenroy’s murder to climb her way back to the top. Fey is well-known for her comedy writing and roles in Saturday Night Live, Mean Girls, and 30 Rock.
Da’Vine Joy Randolph is Detective Williams
With another mystery to solve, Detective Williams is back to begrudgingly help the podcast trio catch the murderer. Williams is once again played by Da’Vine Joy Randolph, who has also appeared in High Fidelity, The Idol, and The Lost City.
Michael Cyril Creighton is Howard Morris
A resident of The Arconia, Howard Morris was first a top suspect in Tim Kono’s murder, but now he is most known for his love of his pet cats. This season, however, we get to see Howard branch out as Oliver’s assistant director. Howard is played by Michael Cyril Creighton, who you might recognize from Dash & Lily, Dexter: New Blood, and The Marvelous Mrs. Maisel.
