Sam Hamm (born November 19, 1955) is an American screenwriter, perhaps best known for writing the screenplay for Tim Burton's Batman and an unused screenplay for the sequel. As a result of his work, he was invited to write for the Batman comic. The result was Batman: Blind Justice, which introduced Bruce Wayne's mentor, Henri Ducard, who later appeared in Batman Begins. Hamm's other screen credits include Never Cry Wolf and Monkeybone. He also wrote unused drafts for Planet of the Apes and Watchmen adaptations.
