* The "Singing in the Rain" dance sequence, the most pure and unpretentious expression of what it feels like to be in love ''ever'' committed to film.
* Cosmo's continued friendship with Don. Don refuses to let stardom get to his head; he treasures his friends. And Cosmo knows that even though he doesn't get the fame that being the best friend of the biggest actor in Hollywood would imply, it's still worthwhile to be with Don.
* Cosmo is possibly the only secondary character in a movie that will be completely fine as a single guy. He sets up his friend with the girl of his dream and doesn't ''once'' try to make a move on Kathy.
** [[{{Adorkable}} He's so embarassed when she kisses him he falls over.]]
* An example which doesn't occur in the movie, but is heartwarming nonetheless: DebbieReynolds was not a dancer at the time she made Singin' in the Rain, and GeneKelly insulted her for her lack of dance experience, upsetting her. FredAstaire was hanging around the studio, and found Reynolds crying under a piano. Hearing what had happened, Astaire volunteered to help her with her dancing.
