How many people can be on the movie poster?
Keep it to a minimal. We do not believe in putting actors or characters on the poster for the hell of it. It is important to understand that only the most pivotal and imperative characters should go on your key art poster - that's your main poster. All the rest of the characters if you believe they are worth promoting with the story on a separate poster then I would suggest putting them on their own character poster. Focusing on the key art is a great way to figure the rest of the characters out. I would suggest putting focus and energy into putting the vibe and story into the key art poster and then the character posters.
