It Happened One Night is directed by Frank Capra and stars Clark Gable and Claudette Colbert. Alan Hale (Sr.) has a small part. It won 1934 Oscar awards for best picture, actor, actress, director and screenplay. The Husband picked this DVD up the other night and picked it for us to watch tonight.
Googlevideo has it online:
Senses of Cinema calls it "The grandparent of the screwball comedy sub-genre, and arguably Frank Capra's best film". FilmReference.com claims it's "One of the most successful films of its time". Salon.com says it's "among the first of its kind, and it's one of the greatest" and that it "still feels unbeatably fresh and shiveringly touching".
