Comedian John Mulaney is set to return to Broadway in the world premiere of 'All In: Comedy About Love,' written by Simon Rich and directed by Alex Timbers, starting December 11 at the Hudson Theatre. Mulaney will lead the cast for the first five weeks, joined by Fred Armisen, Renée Elise Goldsberry, Chloe Fineman, and Richard Kind, with additional casting to be announced. The show features a series of humorous vignettes about relationships, dating, and heartbreak, adapted from Rich's short stories previously published in The New Yorker. Rich and Mulaney, who collaborated on 'Saturday Night Live,' aim for the production to convey the message that the most important part of life is who we share it with. Tickets will go on sale September 26, with a fan pre-sale beginning on September 25. This will mark Mulaney's first Broadway appearance since 'Oh, Hello' in 2016.
