Most watched movie.

Since 1981, I've seen the Chuck Norris film An Eye For An Eye nearly 400 times.

Trevor, have you ever heard the rule that everytime Chuck roundhouse kicks someone you have to down a shot of something potently alcoholic? I think you have a lot of catching up to do.

Dune in the hundreds of times. 

I watched DUNE once, but it felt like hundreds of times . . .

It holds an odd fascination from my youth.  I think I was around 6 when I first saw it.  Couldn't understand it.  I'm not sure just remember it not making sense to me at that age.  Bought it years ago on DVD and watch it pretty frequently.  Wonder why I was confused all those years ago.

I saw it during its original theatrical release. I knew I was in trouble when the woman at the box office handed me a glossary of words and definitions. My most vivid memory is that the movie was long and boring and my ass was killing me from the uncomfortable seats the cinemas had back then.

me and my friend greg used to watch Space Warriors 2000 constantly. I'd guess I've seen it in the dozens of times??? not all the way through though. Its an ultraman movie with some particularly humorous joke dialogue

! No longer available

also used to watch this punk/ new wave doc all the time

I used to watch Back to the Future trilogy (especially the first part) several times a year when I was in my teens and early 20s. Another favourite was Willow (with Val Kilmer). But there isn't really any film that I watch regularly in the last  decade at least.
If TV series count, I watched Babylon 5 (a SF tv series from the 90s) 3 times in the past decade. Considering it's a whole 5 season, over 100 episode series, it probably counts.

I've watched the BRAIN THAT WOULDN'T DIE countless times.
Ditto for The MALTESE FALCON.
