Character mistake: On the train at the beginning of the movie, Colin Firth is talking to Nicole Kidman about Warrington. He states that George Formby was from Warrington and not from Wigan or Formby as people believe. George Formby was born in Wigan.
Suggested correction: He was born in Warrington.
Formby is buried in Warrington, but he was born in Wigan.
Character mistake: When Murphy calls his command, a Marine Staff Sergeant answers the phone as "Sergeant." Maybe in the Army, but a Marine Staff Sergeant would never refer to himself as Sergeant.
Character mistake: Spanish headlines are seen. Some of the a's have the wrong accent on them ("å" instead of "á"). (00:45:25)
