Rebecca Rubin Film and Media Reporter Marc Maron has joined the cast of Universal’s untitled New York Christmas movie, written by Richard Curtis, the Oscar-nominated screenwriter of “Four Weddings and a Funeral,” “Notting Hill” and “Love Actually.” Maron is starring alongside Melissa McCarthy and Paapa Essiedu in the film, a fairy-tale comedy about a workaholic man who enlists the help of a magical genie to help win his family back before Christmas. Sam Boyd, who wrote and created the Anna Kendrick-led HBO Max series “Love Life,” will direct. It’s set to premiere on the NBCUniversal-owned streaming service Peacock on a yet-to-be-determined date.
