For a movie that had to pass the Production Code, My Gal Sal has some pretty racy lines that passed through the censors. Victor Mature obviously has a physical relationship with Carole Landis while working in a travelling vaudeville show, and when he starts coming onto Rita Hayworth when he moves up in the world, he's very interested in in seeing her bedroom. He keeps pushing until she finally relents, and she's next seen in a disheveled appearance running late to her next performance.
The costumes in this movie are gorgeous, so if you like the time period of the 1890s, you'll love watching all the beautiful outfits parade across the screen. The songs are source music from the protagonist's collection, but if you aren't familiar with Paul Dresser's work, there will be new schmaltzy tunes for you to listen to. The love story, honestly, isn't that great. Victor's character is written to be selfishly ambitious with a big temper. Rita is rude, snobby, and also has a huge temper. You can't even imagine the depths of their fights, and it makes the audience wish they'd end up with calmer people who might soften their rough edges. Carole was a sweet, caring girl, and John Sutton is steady, stable, and puts up with way too much from Rita.
But hey, you can't have everything. If you like Rita, you can check out this early musical. It's pure escapism that fits right in with the backstage musicals of the WWII era.
