Billionaire Boys Club is a 2018 American biographical crime drama film directed by James Cox and co-written by Cox and Captain Mauzner. The film is about the social club and Ponzi scheme of the same name. The film stars Ansel Elgort, Taron Egerton, Emma Roberts, Kevin Spacey, Jeremy Irvine, Thomas Cocquerel, Rosanna Arquette, Cary Elwes, and Judd Nelson. The film is based on the real-life Billionaire Boys Club from Southern California during the 1980s, a group of rich teenagers who got involved in a Ponzi scheme and, eventually, murder. The story was previously made into a television film in 1987, which starred Judd Nelson as Joe Hunt. Nelson plays that character's father in the 2018 version.

Originally announced in 2010 and filmed in 2015, Billionaire Boys Club is one of the final works that Spacey filmed prior to numerous sexual misconduct allegations made against him in 2017, and the accusations directly affected the film's release schedule and marketing. The film was released in the United States through video on demand on July 17, 2018, prior to a limited release on August 17, 2018, by Vertical Entertainment, and was a commercial failure. The domestic opening weekend box office take of just $618, from 11 theaters, was the lowest of Spacey's career. The film was panned by critics, although Spacey's performance was praised.
