The Disaster Artist is a 2017 American biographical comedy-drama film starring, co-produced and directed by James Franco. It was written by Scott Neustadter and Michael H. Weber, based on Greg Sestero and Tom Bissell's 2013 non-fiction book of the same title. The film chronicles an unlikely friendship between aspiring actors Tommy Wiseau and Sestero that results in the production of Wiseau's 2003 film The Room, widely considered one of the worst films ever made. The Disaster Artist stars brothers James and Dave Franco as Wiseau and Sestero, respectively, alongside a supporting cast featuring Alison Brie, Ari Graynor, Josh Hutcherson, Jacki Weaver, and Seth Rogen.

Principal photography began on December 8, 2015. A work-in-progress cut of the film premiered at South by Southwest on March 12, 2017; it was later screened at the 2017 Toronto International Film Festival on September 11, and also played at the 2017 San Sebastián International Film Festival, where it became the first American film to win its top prize, the Golden Shell, since A Thousand Years of Good Prayers in 2007.
