Casey Affleck is attached to star in the period noir drama "The Kind One" reports Variety.

Story, set in the 1930s Los Angeles, centers on an amnesiac (Affleck) who finds himself working for a mobster -- a sadistic killer given the nickname "the Kind One" -- and falling in love with the thug's girlfriend.

Based on the just-published novel by Tom Epperson, the author will adapt his novel when the WGA strike is over.
