If you refer to other songs or the song itself, it's not this. This Singin' In The
Rain refers to the 1952 musical film by Gene Kelly and Stanley Donen. Kelly stars as
Don Lockwood and Debbie Reynolds as Kathy Selden.
Don meets Kathy while escaping from his fans and suddenly fell in love on Kathy. Another character, Lina (played by Jean Hagen) has troubles with the sharp
tune of her voice. Cosmo (played by Donald O'Connor) and
Don decide to
dub her, using Kathy's voice, to save her movie. The film received widespread acclaim and praised the performances. National Film Registry marks the film as "culturally, historically, or aesthetically significant". Gene Kelly's dance in the
rain became iconic. Another film, A Clockwork Orange used the song by Gene Kelly.
