I like movies that have lots of changes of costume and scenery. I know it sounds frivolous, but I'm just not into 'serious' movies. I read serious books yes, but not movies. So if there was a movie that would maximize costume and scenery changes, I probably would love it, especially if it was a comedy. Maybe a comedy about actors making a movie where everything goes wrong....!
Since they are making The Avengers, I would like to see if they could make a live-action version of The Justice League. I don't know if it is possible because I don't know if DC Comics own all the rights to all the characters.
