The trailer for Clint Eastwood's latest film, which features the trio of men from the Sacramento area who saved roughly 500 people on a train in France, debuted online Wednesday morning.

The three men — U.S. Army Specialist Alek Skarlatos, Airman 1st Class Spencer Stone, and Anthony Sadler — helped stop a terror attack on a French train in 2015.

The three men play themselves in Clint Eastwood's "The 15:17 to Paris," a film telling the real life story of the brave men's act. According to Warner Bros., the movie follows the lives of the three friends from the struggles of childhood to the events leading up to the attack.

The film is based off the book, titled "The 15:17 to Paris: The True Story of a Terrorist, a Train, and Three American Heroes."
