As part of an ongoing rebuilding process, which producer Lorne Michaels indicated would result in cast changes for the 2014–15 season,[4] a number of changes were announced: Nasim Pedrad departed after five seasons to star on the Lorne Michaels-produced sitcom Mulaney,[5] while John Milhiser, Noël Wells, and Brooks Wheelan were let go after a single season.[6][7] Additionally, Mike O'Brien, a writer for the show for four seasons before joining the cast at the start of the previous season, returned to the writers' room.[8]
