John Mulaney is stepping into a massive tradition with his new sitcom, “Mulaney,” which premieres on FOX Sunday, Oct. 5 at 9:30/8:30c. He’s a successful standup comedian who has now turned to creating his own sitcom with an eponymous title and character, as well as a multi-camera format (meaning several cameras are used simultaneously to record). That’s a lot of pressure to take on, especially with so many eponymous sitcoms featuring standup comedians as examples.
