Failed cartoonist Sam Hamm turned to screenwriting when he realized he would never be able to draw like Alex Toth. His feature credits include Never Cry Wolf, Batman, Batman Returns, and Monkeybone.

Hamm also created the short-lived television series M.A.N.T.I.S. in collaboration with Sam Raimi. Most recently, he has written two episodes of the cable series Masters of Horror for director Joe Dante: Homecoming (for which he won a Best Screenplay award at the Sitges International Film Festival) and The Screwfly Solution.
