Cartoons: City Mouse goes to the movies

I've mentioned how I recently spent a year living in Columbus. While I was there, I did an autobiographical comic strip for a local newspaper called City Mouse Goes West, about my many adventures in this Midwestern city. (Yes, I represented myself as an anthropomorphic mouse. It seemed like a good idea at the time.) This is one of the strips I did, in which I inserted my cartoon avatar and one of my recurring characters, Collie the Columbus Cow ('cause they say Columbus is a cowtown - get it?) into six different movie posters from 2008. (Click on it to enlarge.) Can you recognize them all?
