Very short clip of Charlie and his date, Georgia Hale, at the Hollywood premiere of Hell's Angels, May 1930

The film starred Jean Harlow (who appeared as an extra in City Lights which CC was making at the time. Her footage was later cut but photos still exist of her appearance). See footage of other stars at the premiere, such as Dolores Del Rio and Buster Keaton, here. Of course, Charlie is the only one who doesn't stop and talk.
