3. Quentin Tarantino
Yeah, okay, I know. I really don't know where to start on how this would be a good idea. Tarantino's writing style could be very applicable to a Justice League movie. He takes several stories revolving different characters and weaves them into one epic tale of violence and humour. His stories are often overly saturated with "fantasy" elements that create more of a fairy-tale setting them the crime-drama that they are meant to be. I'm not sure how keen Quentin Tarantino would be to take a stab at the writing of a Justice League movie, or a film based on any comic character. He's recently gone on record about how uninteresting he finds Batman as a character. Now this could just be his feelings on the one character, but maybe super heroes just aren't his cup o' tea. Still, if heroes aren't his thing, what about villains? I could see him writing for villains such as Lex Luthor, Black Mask, Metallo, Joker. I admit to being more curious than anything about how his script would read.
