I saw a movie one time about 6 or 7 years ago, and I cant find it anywhere.
I remember the guy goes into an airport with a musical box and bomb making stuff, gets through security, goes into the bathroom, assembles the bomb, and goes into the airplane. He sits in his seat, and when the coast is clear, goes to the last seat in the back, puts the bomb underneath the seat, goes back to his seat, says hes not feeling well and gets off the plane.
Not much else I can remember...and I don't know the actors. Anyone know?
