Movies you HAVE to watch whenever they're on.

Anything directed by Sergio Leone.

MANY many movies like that! Right now... Accepted, with Justin Long, Jonah Hill, Adam Herschman. Inane but hilarious teen movie. Inspiring even.

The only one I can really think of that I have to watch is Bull Durham.

Lots of great movies here, but here's a few that I can think of:
Shawshank Redemption
The Green Mile
Bull Durham
Field of Dreams
Crimson Tide
Gladiator
Young Frankenstein

Young Frankestein is that perfect example. Its not a great movie but if it is on, there is no way a good person cannot watch it.

Casablanca, The Big Sleep, and The Natural.

I happened to flip on The Natural last night on TCM, at 10:20 at night, but only 6 minutes into the movie. I really hesitated to start watching, because I knew if I watched for more than 5 minutes, I'd watch it all the way through to the end. But I couldn't help myself. On TCM, with no commercial interruptions, there was no way I was going to be diverted. I was up until 12:30 watching it, again.

There are so many reasons I love this movie. Great music, and used really well. Great cinematography. A fantastic feel for capturing the time period in which the movie is set. The acting is top-notch in my opinion. Every scene in the movie has a purpose. And, the story is really compelling. The whole movie so full of imagery that the "unrealistic" feats on the field just naturally fit right in. Finally -- and it goes without saying that this is one of the reasons I love it -- it is about baseball.

I hope it's not on again tonight. I need some sleep.
