Kick Ass was a great movie. And the comic itself was pretty great as well. Both the movie and the comic were pretty close together in their stories. The movie didn't stray too far from what was happening in the comic save for a few things. But with Kick Ass 2, this should get interesting.
I won't spoil much but the Kick Ass 2 comic is pretty brutal and graphic. It's a good sequel but as I read the comics I couldn't help but think how in the world they will try to turn this into a movie, but it appears Universal has given the greenlight to director Jeff Wadlow who also wrote the script to make the movie come to life. Filming will begin this Fall.
