Samuel Baum has signed a two-year exclusive cable writing and producing deal with HBO. The pact comes on the heels of HBO Films greenlighting The Wizard Of Lies, the Bernie Madoff movie starring Robert De Niro on which Baum was a writer. The film about the disgraced financier has been shooting in New York with Barry Levinson directing.

Baum recently co-wrote and executive produced the Amazon pilot Cocked. He previously created and executive produced the Fox drama series Lie To Me. Baum is repped by CAA and attorney Jamie Mandelbaum.
