Depends. Strictly for the movie, for his role in it, or....
Anyway, The Longest Day is a favourite of mine, definitely, or Indiana Jones 3 (and he'll be back for Indy 5...Oh dear, I'm sort of on the fence between horrified and hopeful). The Hunt for the Red October's pretty awesome.
Going down the line, there're Dragonheart or the Rock, which weren't particularly great movies, but I liked him in it. Then there's the League of Extraordinary Gentlemen, which, I'm supposed to say sucked, but is a guilty pleasure of mine :-P
It's odd, but I haven't seen a single of his James Bond movies
