'It Happened One Night'
"It Happened One Night" premiered in 1934, but the movie is still funny for today's audiences. After her rich father has her marriage annulled, spoiled socialite Ellie Andrews -- played by Claudette Colbert -- takes a bus from Miami to return to her love in New York. Enterprising news reporter Peter Warne (Clark Gable) discovers her identity and agrees to help her reach her destination if she'll grant him exclusive rights to her story after it's all over. The dialogue is witty, sharp and hilarious, and the film's influence on the comedy genre has been profound.
