Calling all Arconiacs: Only Murders in the Building season 3 is here (and it's a musical!). Hulu's murder-mystery comedy has returned for a showstopping third installment, following that epic Only Murders season 2 finale flash-forward. In case you need a refresher, this season's mystery will center the mysterious death of Ben Glenroy (Paul Rudd), the star of Oliver's (Martin Short) new Broadway show Death Rattle. After Ben collapses and dies in the middle of opening night, Charles (Steve Martin), Oliver, and Mabel (Selena Gomez) will bring back their podcast to investigate the case and find the killer hidden among the show's cast.
To take OMITB outside of the Arconia, the series has assembled a stellar cast for its third season, which includes several Broadway stars and some beloved television and film actors. Read on for our running list of all the guest stars and celebrity cameos in season 3.
