I definitely need to go with The Unbearable Weight of Incredible Talent. That's the funniest movie I've seen in years. The LSD scene had me and my wife in stitches. I haven't laughed that hard, and that genuinely in so long.
A few friends and I will get together periodically to watch a Nic Cage movie. Depending on the vibe of our selection, we call our viewing party either "Cage Rage" or "Nic at Night". It started off with us just watching weird/essentric movies, but since weird films and films with Nic Cage tend to have a lot of overlap, it became Cage centered. Mandy and Pig were the two that really kicked it off (Pig is probably my favorite so far). We actually just watched Vampire's Kiss last night-- mainly to know where the meme comes from, but it was a very entertaining dark comedy. The first ten minutes he feels a little out of place and maybe miscast, but then it slowly spirals and you realize how perfect he is for the role.
