Superman Returns (I know it wasn't as popular or as good as a few of the other Superman movies but I still enjoyed it, thought the guy they got to play Superman did a great job)
Superman: The Movie & Superman II
Batman, Batman Returns
Batman Begins, The Dark Knight
Spider Man I, II & III
The Hulk (The most recent version)
I am mostly into the DC & Marvel comics, never really got into the stuff from the companies like Dark Horse and stuff. My brother I think got into that stuff a lot more... he was always more of the comic fan anyway though. I do have both of the original KISS Comics that they made back in the late 70's though.. not sure what they are worth now but I know the first one was worth over $100 for a long time.
I see you mentioned Kick Ass, I enjoyed that one too.. seen it twice. Did you watch the Losers? I hadn't realized that was based on a comic as well. I enjoyed that movie as well, if ya haven't watched it yet, might be worth seeing.
Its cool that on Sirius radio they have a station that plays old radio serials. Once in awhile they will do special weekends or days where they have a topic. I'm sure they have had The Shadow serials on there at some point or another.
