Break out your tap shoes! Call Debbie Reynolds! And get a look at this excellent collection of 25-Things-SITR trivia from Moviefone.com, including:

1. The original title was “Excess Baggage.” (Alicia Silverstone wonders what if Donen had gone there.)

3. Screenwriter Betty Comden remembered producer Arthur Freed told her and partner Adolph Green: “‘Kids, you’re going to write a movie called ‘Singin’ in the Rain.’ Just put all of my songs in it.’ All we knew was there would be some scene where someone would be singing, and it would be raining.”

9. and 11. Legendary dancers Fred Astaire, Gwen Verdon, Carol Haney, and Jeanne Coyne were all involved in minor but memorable ways. (Fosse alert!)
