Filming for the movie, in which Gable and Colbert's characters have to travel together from Florida to New York by whatever means available, began in a tense atmosphere; nevertheless, both Gable and director Frank Capra enjoyed making the movie. "It Happened One Night" became the first movie to sweep all five of the major Academy Awards, with Gable winning for Best Actor and Colbert for Best Actress. "Critics praised the fast-paced farce that would enter in a whole new romantic genre: the screwball comedy." The movie opened slowly at the box office, but once word of mouth spread it became a big hit, with men's underwear sales plummeting because Gable didn't wear an undershirt in the movie.
