Continuity mistake: Towards the end while Brian and Welch are talking at the hotel, the sun on the wall changes between shots.
Factual error: During the opening credits a newspaper is shown welcoming the "49th" state. The movie is set in Hawaii and Alaska is the 49th state. Hawaii gained statehood in August 1959, Alaska in the January of that year.
Other mistake: Whilst the main character is having a 'talk' with the general, the world clocks on the way show 3:50 on time 1, and 3:49 on time 2. (01:25:10)
