I absolutely love this too! And end up watching it every time it's on!
And that's kind of the way I tend to re-watch movies - accidentally flick onto one on the sky movie channels or catch it advertised in the planner. Never pre-meditated, so it's hard to list certain one's I've picked out as a constant re-watch.
You guys talking about Rocky - I was very surprised at the final Rocky film - really enjoyed it, although the actor who played the "champ" didn't seem to fit in with the rest of the film.
