Fan Casting The Comedian

It is a serious and atmospheric drama with comedy elements with Robert Pattinson's comedy and personality, but added serious elements on top of that, where a stand-up comedian gets down on his luck, he isn't doing his best and he can't get a gig anywhere, so he has to do some unconventional/morally obscure things where you can't tell right from wrong to get what he wants, he eventually gets what he wants in the end, but he also sees that stand up comedy isn't really for him, but he can't leave because of what he did, so he ends up doing what he doesn't want to do. He later learns that he can't leave it, he doesn't do anything about it because he can't, so he just lives doing what he doesn't want to do, which makes him sad and depressed, and something back eventually happens because of his sadness and depression.
