One of the film posters for the Dark Knight

1. The movie title is at the bottom of the poster.
2.Yes the are Batman (Christian Bale),Joker (Heath ledger) and Harvey dent(Aaron eckhart)
3.The design is to show the mood which is dark and scary.
4. The three characters are holding different objects.
5. The only text show is the title and the writing on the badge.
6. The faces of half the characters are covered up.
7.I think it is really persuasive because it shows the mood and tone of the film, also giving away the key villian of the film.
