Only Murders in the Building season 4 cast
It can't be Only Murders in the Building without Selena Gomez, Steve Martin and Martin Short, as the trio of actors have proven to be a great on-screen team. A critically-acclaimed one too, as all three have earned Emmy nominations for their performances (Short three times, Martin twice and Gomez once).
Other familiar faces are also set to return, including Meryl Streep, who played Loretta Durkin in season 3, at least for a guest spot, and Jane Lynch, will pop up in flashbacks as Sazz.
Meanwhile, long-time fan favorites Detective Williams, played by Oscar-winner Da'Vine Joy Randolph, and Howard (Michael Cyril Creighton) are definitely coming back. It's unclear if we're going to see other Arconia residents like Uma (Jackie Hoffman) and Jonathan (Jason Veasey), as well as Ryan Broussard as Oliver's son Will, as they haven't been officially confirmed.
New cast members set to appear in Only Murders in the Building season 4 include Eva Longoria, Molly Shannon, Eugene Levy and Kumail Nanjiani, Zack Galifianakis, Richard Kind and Melissa McCarthy as guest stars. Some new series regulars include Desmin Borges (You're The Worst), Siena Werber (Brand New Cherry Flavor), Lilian Rebelo (Our Dear Drug Lord), Daphne Rubin-Vega (In the Heights), Catherine Cohen (The Lovebirds) and Jin Ha (Pachinko).
It was recently confirmed that one season 3 cast member will not be back: Jesse Williams confirmed he is not on the show this season. As for other familiar faces, we haven't heard if Andrea Martin's Joy, Charles' jilted former fiance, is returning, or anything about Amy Ryan as Jan, who was referenced to still having a relationship with Sazz in season 3.
