I saw the first Austin Powers like 10 times, and the first Matrix like 12 times. I took EVERYONE I knew to see that movie.
Last movie I saw more than once would have been Matrix Reloaded. I saw it twice. Since then, I've not had the time to see any movies in the theater unless I HAVE to see it. The last movie I even saw was ROTK, I believe. I can't think of a movie I've seen in theaters this year yet.
