Dazed and Confused, Sideways, Harry Potter movies, Lord of the Rings Trilogy, Underworld movies.

Idiocracy
I nuovi mostri: First Aid (Not available in English I'm afraid)
They lives
The gost in the shell (Anime, not the crappy remake)
Lamu: Beautiful Dreamer

I've always been a rewatcher of movies. The local theatre where I grew up would let you stay for the second showing (there were only ever two showings) so a friend of mine and I took serious advantage of that. I saw the first Star Wars six times. Young Frankenstein four times (and my kids and I watch YF almost every Halloween). The list would be obnoxiously long. The Holy Grail is on...about a semi annual rotation. As far as newer movies go I've seen Deadpool an obnoxious number of times. Baby Driver is outstanding as a movie and as a soundtrack. John Wick has seen a few replays as well.

Silence of the Lambs
Gladiator
Interview with a Vampire
Gone in 60 Seconds
The Green Mile
Bram Stoker’s Dracula

BTW, I'm loving everyone's movies!!!! So many good ones!

Clue, Goonies, Monty Python and the Holy Grail, Saawariya, Children of The Corn.

Simon of the Desert, Persona, Grand Illusion, Jules and Jim, all the Monty Python films, and that YouTube video of the little girl snatching the bread out of a bird's mouth. . .

The Godfather I & II

Definitely, Shawshank, but also Hunt for Red October, The Godfather, Matrix, Lock Stock & Two Smoking Barrels, Remains of the Day, Howard's End, Dances with Wolves, and there are more.

I would say "The Godfather". I've probably seen it ten times or more.
