Mark Hanna

Mark Hanna (January 1, 1917 – October 16, 2003) was an American screenwriter and actor. He was known for writing the screenplays for many science fiction B movies in the 1950s, particularly Attack of the 50 Foot Woman.

Hanna's family first moved to Palm Beach County when he was one year old. He attended Palm Beach High School, worked in his father's produce store, and served in the US Navy during World War Two. Hanna then decided to go to Hollywood and changed his name from "Emil" to "Mark".

Hanna worked as an actor for several years before trying screenwriting after breaking his leg before he was to appear in the Western Backlash. His first script was Requiem for an Outlaw based on the Florida Ashley gang.

Hanna's first major screenplay was Gunslinger in 1956. This was the first of five scripts on which Hanna is credited with Charles B. Griffith, although Griffith later claimed that he did most of the writing while Hanna did the selling. Hanna continued to be prolific through the mid-1960s, after which his film credits become sporadic. His last screenplay was for Star Portal in 1998, five years before his death from stroke complications.
