Which movie have you watched more than any other?

[The Burgomaster]

For me, it's THE GODFATHER.  I saw it at the drive-in, on VHS, cable, DVD, and regular television (for awhile, they showed THE GODFATHER: THE COMPLETE NOVEL FOR TELEVISION, every year.  This is a re-edited version of the first two GODFATHER movies assembled into a mini-series).  I have seen many movies multiple times, but none nearly as many times as THE GODFATHER.  Some others on my "watch them over and over" list are:

* WAR OF THE WORLDS (Gene Barry version)
* JOURNEY TO THE CENTER OF THE EARTH (James Mason version)
* DELIVERANCE
* TAXI DRIVER
* NIGHT OF THE LIVING DEAD (original)
* DAWN IF THE DEAD (original)
* DIRTY HARRY
* THE FRENCH CONNECTION
* SHAFT (original)
* BULLITT
* SCARFACE (Al Pacino version)
* PAPILLON
* MONTY PYTHON AND THE HOLY GRAIL
* Plenty of others!

Which movie(s) have you watched ad nauseam?
