Danny Kaye & Bing Crosby performing “Sisters” in 'White Christmas', 1954 ————————————————————————- Bing Crosby and Danny Kaye's comedy act wasn't originally in the story. They were goofing around, though, and director Michael Curtiz found it so hilarious that he wrote it in. Apparently, the actors found it comical, too: The laughing during the number is real. The take in the film was the best one they could get of the two, who kept cracking each other up. ————————————————————————- #oldhollywood
