Warner Bros. has added three movies to its 2016 slate, issuing new release dates for The Accountant (January 29, 2016), Arms & the Dudes (March 11, 2016) and Project XX (August 19, 2016), a sequel to the 2012 found footage comedy Project X. The original Project X starred Thomas Mann as a teenager who throws a high school party that gets wildly out of control, and is all captured on video. It isn't known if any of the original cast members, or director Nima Nourizadeh, will be back for the follow-up at this time. Project XX will go up against Focus Features' animated comedy Kubo and the Two Strings on August 19, 2016.

The Accountant has Ben Affleck, Anna Kendrick and J.K. Simmons attached to star, centering on a forensic accountant who moonlights as a deadly assassin. Gavin O'Connor is directing the thriller from a script by Bill Dubuque (The Judge). The Accountant is currently in post-production, and is slated to go up against Disney's The Finest Hours and 20th Century Fox's animated sequel Kung Fu Panda 3 on January 29, 2016.

Arms & the Dudes, which started filming last month, is based on the true story of two friends (Jonah Hill and Miles Teller) who exploit a government initiative that allows small businesses to bid on government contracts. They end up becoming contracted by the Pentagon to sell arms to American allies in Afghanistan during the Iraq War. Todd Phillips is directing from a script he co-wrote with Jason Smilovic. Arms & the Dudes will go up against STX Entertainment's The Free State of Jones, Focus Features' Christ the Lord and an untitled Bad Robot production on March 11, 2016, which is also two weeks before Warner Bros.' Batman v Superman: Dawn of Justice hits theaters. The studio has also pushed an untitled New Line Cinema horror film from January 29, 2016, to January 22, 2016.
