Some bad ones...
1) The whole movie 'Red Eye'. The only saving grace was Rachel McAdams delicious looks!
2) 'Snakes on a Plane' - utter tripe and the aircraft scenes were so riddled with errors. 747 upper deck was like a widebody with a staircase at the front and back! There were scenes of an ATC scope in full colour with the planes travelling near LA at about 3000mph!
3) 'Catch Me If You Can' - when Frank Abagnale is flying back from France with the Tom Hanks character it shows an Airbus of some kind landing...despite the fact the film is set in the 1960s and it showed a 707 (IIRC) in other shots. Also they were landing on runway 44 at La Guardia (?)
4) 'The Holiday' - Cameron Diaz's character flies on a BA 777 from LAX-LHR...BA have only ever flown the 747 on the route.
