Fox’s upcoming sitcom Mulaney, created by and starring standup John Mulaney, has started lining up guest stars. Penny Marshall and Lorraine Bracco have been cast as a lesbian couple who will appear in the show’s second episode, TV Line reports. Marshall and Bracco will play Tutti and Vaughn, friends of Mulaney’s neighbor Oscar (played by Elliott Gould). The series stars John Mulaney as an aspiring standup who writes for a game show hosted by Lou Cannon (Martin Short) and lives with rommate Jane (SNL’s Nasim Pedrad). The series, which NBC passed on last spring, is expected to premiere on Fox later this year.
