Lonesome EJ, you took the words right out of my mouth about the Peter Sellers films. I would watch any of them again. My particular favourites, which I have rewatched and would watch again and again are:

The Party (probably my all-time favourite)
The Pink Panther Strikes Again (his best Pink Panther IMO)
I Love You Alice B Toklas

Other movies include:

Harold and Maude
Carry On Regardless
One Flew Over the Cuckoo's Nest
The Witches of Eastwick (in fact, just about anything with Jack Nicholson)
Phenomenon
Pontiac Moon
The Eighth Day (delightful French film)
Raising Arizona

and probably lots of others I can't recall right now.

Also anything Monty Python, Fawlty Towers, the TV series of Hitchhikers Guide to the Galaxy and in the future, I think I will want to see the Harry Potter films and LOTR films again too.
