The Joker
Another beloved character who despite his darkness and complete and total lack of empathy has captured the hearts of fans everywhere for decades. We were hesitant to put him on this list because of Heath Ledger's great performance in the Dark Knight and Jared Leto's upcoming chance to blow us away in Suicide Squad's release this summer. But we couldn't help but imagine not only a movie where Joker is the lead, perhaps allowing us to even cheer for the maniac for once, but also one that lets his brutality loose. In the world of R rated comic book movies, the Joker could own the genre.
It's hard to say that this may ever happen. Batman is of course a favorite among children and so the Joker falls into that category of fandom, whether he likes it or not, but the sheer brutality of the Joker in other forms like the Batman comic book "A Death in the Family", and the scene’s subsequent appearance in Under the Red Hood, where he beats Robin to death with a crowbar. The Under the Red Hood clip is relentless and long and actually pretty difficult to watch.
While Ledger captured the insanity of the Joker, another film to focus on just how deep his darkness goes could be great– and terribly haunting, disturbing, and brutal.
