The 15:17 to Paris is a 2018 American biographical drama film produced and directed by Clint Eastwood and written by Dorothy Blyskal, based on the 2016 autobiography The 15:17 to Paris: The True Story of a Terrorist, a Train, and Three American Heroes by Jeffrey E. Stern, Spencer Stone, Anthony Sadler, and Alek Skarlatos. The film stars Stone, Sadler, and Skarlatos as themselves and follows the trio through life leading up to and including their stopping of the 2015 Thalys train attack. Judy Greer and Jenna Fischer also star.

Eastwood's intention to adapt the autobiography into a film was announced in April 2017, from a screenplay by Blyskal, a first-time screenwriter. Though professional actors such as Kyle Gallner and Jeremie Harris were considered, Eastwood decided by July to instead cast the real-life participants of the event, and filming began in the same month.

The 15:17 to Paris was released in the United States on February 9, 2018, by Warner Bros. Pictures. It received negative reviews from critics, who faulted the screenplay and unengaging story before the climax, and the acting from the lead actors, while the central train sequences were generally praised. The film grossed $57 million worldwide against a production budget of $30 million.
