Don Lockwood (Gene Kelly)’s Timeline and Summary

At the premiere of his latest hit movie, Don tells the crowd his life story. One problem: It's all fiction.
Don tries to convince Lina that they're not a couple just because the press says they are. It doesn't work.
Don meets Kathy. She tells him she's a stage actress and that she thinks stage actors are more dignified than film actors. He's upset.
At R.F.'s party, Don sees that Kathy's actually a dancer. He's intrigued. She runs away, embarrassed.
R.F. tells Don that his next flick, The Dueling Cavalier, will be a talkie.
Don tries to find Kathy for weeks and fails, only to run into her on set.
Don takes diction lessons.
Don and Lina shoot The Dueling Cavalier. It's plagued by sound problems.
Don and Cosmo convince R.F. to turn Cavalier into a musical. Kathy dubs over Lina's horrendous voice. The movie's a hit.
When Lina threatens to ruin Kathy's career by forcing her to be her voice forever, Don threatens to walk.
Don, Cosmo, and R.F. expose Lina as a fraud to the audience at the Cavalier premiere.
When Kathy tries to flee, embarrassed once again, Don wins her back by telling the crowd that she's the real star of the movie.
Don and Kathy co-star in a film called Singin' in the Rain. How meta.
