'Singin' In The Rain'

For one, what specimens Gene Kelly and Donald O'Connor are. Just freaks of nature, who have more talent in their left big toe than all of Hollywood today. (Then again, would we really enjoy our Brad Pitts and George Clooneys to be dancers, singers and general hams? Hardly.)

Secondly, for the record, the Kelly and Debbie Reynolds characters (Don Lockwood and Kathy Selden) eventually star in a film titled "Singin' in the Rain."

So, is that the same exact film that I just watched? Or is that a totally different film about singing in the rain. Would I enjoy that movie more or less than this "Singin' in the Rain"?
