Mortimer Offner (November 3, 1900 – September 1965) was an American photographer, political activist, and screenwriter.
[1] His parents were of Austrian Jewish descent and they ran a dressmaking business and lived with Mortimer's aunt on East 54th street.
Dorothy Yost and Jane Murfin had created a script, but the director George Stevens was annoyed that the writers had changed the ending.
Stevens' friend, Offner, was called in, and they and Hepburn rewrote it, writing and performing the lines as they wrote.
Like many, including his cousin's husband Edward Eliscu, Mortimer moved away from Hollywood and returned to New York.
