What movies could you pick to watch over and over again?

I watched Apollo 13 last night for the millionth time for no reason other than I love the film; the jeopardy, the science, the problems and solutions and possibly one of the most tense waits in cinema waiting for the radio blackout to be over.

The Lord of The Rings trilogy is another.

The Sum of All Fears, Saving Private Ryan, Master & Commander, the new Star Trek films with Chris Pine are others I really enjoy on repeat.
