Right, apart from the submarine films I've listed up thread, there are:
Ronin
Local Hero
It's a Wonderful Life (every Christmas, without fail, in black and white - none of that 'colourised' nonsense)
The 39 Steps (the original one - the Kenneth Moore one is tolerable, certainly not the Robert Powell one and definitely not the Rupert Penry-Jones one)
Con Air (Nic Cage's finest 2 hours on screen)
Bringing Out The Dead (a very different Nic Cage film)
Shawshank Redemption
Goodfellas
Pulp Fiction (still Quents finest work)
Once Upon A Time In Mexico (a rare Johnny Depp film that isn't pants)
The Matrix (the original ("I know kung-fu"), not the bobbins sequel and threequel)
Heat
Star Wars (Episode IV, if you must)
Gladiator
Blade Runner
Clint's Spaghetti Westerns
And there are bound to me more I've forgotten to list.
Guilty pleasures? Most stuff by Luc Besson, a lot of the stuff on the SyFy channel that is clearly "inspired" by something made by someone else - and the Sharknado movies, obvs.
Honestly, if it wasn't for the bike I could easily spend every weekend watching movies.
