U-571 is a 2000 submarine film directed by Jonathan Mostow from a screenplay he co-wrote with Sam Montgomery and David Ayer. The film stars Matthew McConaughey, Harvey Keitel, Bill Paxton, Jon Bon Jovi, Jake Weber and Matthew Settle. The film follows a World War II German submarine boarded by American submariners to capture her Enigma cipher machine.

Although the film was financially successful and received generally positive reviews from critics, winning the Academy Award for Best Sound Editing, the fictitious plot attracted substantial criticism. British sailors from HMS Bulldog captured the first naval Enigma machine from U-110 in the North Atlantic in May 1941, seven months before the United States entered the war and three years before the US Navy captured U-505 and its Enigma machine. Anger over the film’s inaccuracies reached the House of Commons, where the Prime Minister, Tony Blair, called the film an "affront" to British sailors.
