'Singing in the Rain' is one of those movies that's like a human test. If someone doesn't like that movie, then there's a good chance they are some sort of alien or robot. They could even be an alien-robot, or a robot-alien, which are two very different things. What I'm trying to say is that 'Singing in the Rain' is a cute, classic movie that everyone should love. Cyd Charisse is one of the stars of the film, and has a long list of singing, dancing, and acting credits.
Everybody loves a great pair of legs. Legs are important for an actress, especially if one of your skills is dancing. Brooke Shields insured her legs and she doesn't even dance. Actresses just need legs that look good, but a dancers' actually have to work. What a burden.
