U-571?

In 2006, screenwriter David Ayer admitted that U-571 distorted history and stated that he would not do it again.[8] Ayer told BBC Radio 4's The Film Programme that he "did not feel good" about suggesting Americans captured the Naval Enigma cipher rather than the British.
“It was a distortion...a mercenary decision...to create this parallel history in order to drive the movie for an American audience. Both my grandparents were officers in World War II, and I would be personally offended if somebody distorted their achievements."

Not for accuracy that's for sure
