Pain & Gain is a 2013 American black comedy action crime film directed by Michael Bay and written by Christopher Markus and Stephen McFeely. It is based on a 1999 series of Miami New Times articles by Pete Collins about the activities of the Sun Gym gang, a group of bodybuilding ex-convicts convicted of kidnapping, extortion, torture, and murder in Miami in the mid-1990s. It stars Mark Wahlberg, Dwayne Johnson, and Anthony Mackie as members of the gang, with supporting roles played by Tony Shalhoub and Ed Harris. The title is a play on the fitness adage "no pain, no gain".
