How many movies have you watched more then once

Forbidden planet, great movie to watch multiple times.
The classics, Citizen Cane, any Humphrey Bogart, Casablanca, Maltese Falcon and To have and have not, are top of the list.
The first of the Thin Man series
Young Frankenstein we have just seen on the large screen.
And for western's, Once upon a time in the west.
Wife and I love old movies.
