1) Red Eye
This movie is a proper thriller. It has the perfect run time too, short, but intense throughout so it never gives the opportunity to drag. Cillian Murphy probably gets side eyed on every flight he's on now.
Everybody is going to pick this movie. It's so stupid and fun.
3) The Aviator
Unlike Red Eye, this does get the opportunity to drag but it's so well made and acted that I don't care. The cast is amazing.
