Written by Taylor Jenkins Reid (New York Times bestselling author of Daisy Jones & The Six) and Ashley Rodger, and directed by Kay Cannon (BLOCKERS), MY EX-FRIEND’S WEDDING follows four childhood best friends who get a drunken voicemail from their former best friend on the eve of her wedding day — confessing that she thinks she's making a mistake. From there, they set out to stop her wedding and rekindle the friendship they once shared.
