SINGIN' IN THE RAIN

With the exception of few, Singin' in the Rain is the one of the best movies ever. The movie is a combination musical, slapstick comedy, and romantic drama. Starring a hilarious Donald O'Connor, the amazing dancin' and prancin' Gene Kelly, and the adorable Debbie Reynolds, is a charming, up-beat, graceful and thoroughly enjoyable experience with great songs and wonderful dances. Some of the best songs in this movie include: Make 'Em Laugh, You Were Meant for Me, Good Morning, Would You?, You Are My Lucky Star, and Steppin' out with my Baby

Kelly with the then 18-year old Reynolds (now sporadically appearing as Karen Walker's mom on Will & Grace)

The plot of the film is actually an autobiography of Hollywood itself at the dawn of the talkies. The story is about a dashing, smug but romantic silent film star and swashbuckling matinee idol, Don Lockwood (Gene Kelly), and his glamorous blonde screen partner/diva Lina Lamont (Jean Hagen) who are expected to pretend to be romantically involved with each other. They are also pressured by the studio boss R.F. Simpson (Millard Mitchell) to change their silent romantic drama (The Duelling Cavalier) and make a sound picture, the musical The Dancing Cavalier. There's one serious problem, however - the temperamental, narcissistic star has a shrill, screechy New York accent. The star's ex-song-and-dance partner Cosmo (Donald O'Connor) proposes to turn the doomed film into a musical, and suggests that Don's aspiring actress and ingenue dancer-girlfriend Kathy Selden (Debbie Reynolds dub in her singing voice behind the scenes for lip-synching Lina. The results of their scheming to expose the jealous Lina and put Kathy in the limelight provide the film's expected happy resolution.
