While Hulu’s Only Murders in the Building already boasts one of television’s most packed casts, it seems the show is planning to further round out its A-list ensemble in its upcoming fifth season with two-time Oscar winner Renée Zellweger joining the party. Although plot points and character details remain under wraps, Deadline reports that Zellweger will be joining Christoph Waltz and Keegan-Michael Key as this season’s newcomers alongside main cast Steve Martin, Martin Short, and Selena Gomez returning. Production on the fifth season of Only Murders in the Building started this week in New York according to the outlet, so hopefully fans won’t have to wait too long before sinking their teeth into the show’s next whodunnit. One remaining mystery is whether Short’s on-screen (and rumored real-life) love interest Meryl Streep will reprise her role in the show after her character was shipped off to New Zealand at the end of Season 4. “Nothing would make me happier than more Meryl Streep in the show,” showrunner John Hoffman said this week.
