One of my favorite movie eras is the early talkies, where they hadn't quite figured out how to take advantage of the new technology. There was a run of fairly rotten (but entertaining) musicals that appeared to be a random collection of vaudeville acts. You can tell them because they have the year in the title, like The Broadway Melody of 1929 and The Big Broadcast of 1936. And it occurred to me recently that Singin' in the Rain is essentially about making a movie in that era. So it was time for a rewatch!
...and it's still good. I think Donald O'Connor's character actually comes out better than Gene Kelly's does. Kelly is just a movie star, but O'Connor is pput in charge of the studio's new music department. That's a pretty good gig!
