5. There's Some Comic Differences
If Kick-Ass impact was like Watchmens, then its creation can be likened to another work that went on to define a medium. When Stanley Kubrick was making 2001: A Space Odyssey he worked directly with Arthur C. Clarke who was writing the novel companion. Oddly enough a very similar process was at work with this subversive superhero tale. Mark Millar was already well into creatinghis comic book when Matthew Vaughn began work on the film, but the development of the big screen version did have an impact, the story changing on both sides as production moved on. There were still some marked differences (Big Daddys real backstory being a particularly interesting one), but through the similarities (and incredibly minor differences) it was clear the film and comic book had a shared genesis. The sequel had less of an impact on the print version (although is one pretty major thing that will go on to affect Kick-Ass 3 later in this list), to the extent where the film deviated from the comic at many points. Most of this is related to some extremely shocking violence that wouldn't translate well on to the big screen, most notably the scene in the above image; instead of struggling to get it up, The Motherf*cker succeeds in his rape.
