Cannot believe you haven't seen the movie. It's great!
Haven't seen Cal either. From what I recall Last Exit is good, but very dark and I don't intend watching it again as it's not exactly entertaining. Local Hero is the best and Wag the Dog is good too IMHO.
The princess bride is very very entertaining, with lot of humour (Billy Crystal small scene is great), action, and of course love, but humour is the principal ingredient of the film.
Cal is ok. A strange story with the Irish conflict in the middle. It's very interesting how the music flows. Actually, there is music in the film that is not in the released OST...
Last exit is... well. I saw it at least twice with lot of years between, and it's too much for me. The music fits perfectly with the movie but some scenes are really too much.
My advice, watch the princess bride and cal. You will like it, at least the humor of the first one!
