Just finished
Ziegfield Girl(1941), pretty much just to see Judy Garland. It also stars James Stewart, Lana Turner and Hedy Lamaar. Not sure if I've seen a Lana Turner movie before and I've definitely never seen Hedy Lamarr in anything before. Even though Lamarr's role isn't very large, she has a strong, understated presence with her limited time on screen. Just checked my local library and they don't have any movies by either of these ladies.

But there are two other library systems that carry older movies, so I'll have to check out more of their work in time.
Anyway, I thought Ziegfield Girl was pretty strong. More a story movie than a forum to present various musical and dance numbers. Basically showing the rise (and fall, in one circumstance) of the three female leads. Turner's role is the biggest, I'd say, even bigger than first-billed Stewart. But for me, there were two highlights, one dance number and one musical number. The dance number was near the end of the movie and I thought I'd post a link to it, but I actually can't find any information about it at all. It was a strong Latin number, but that's all I can tell you. And the strongest moment goes to Garland, because of 1) that voice, 2) that star power, 3) that song and 4) the moment...where a teenage girl and her father have been rejected for their performance because of the father's uber-uptempo version of the song...and when Garland's character is given a second chance to audition, she has to go with the version she suggested to her father (and he rejected):
Judy Garland sings "I'm Always Chasing Rainbows" from "Ziegfeld Girl"
Garland was always so great and making one wonder where they heck they left their hanky....

I think 1945's Ziegfield Follies was stronger than this movie, but both are recommended. Too much star power to say no to any of the Ziegield movies (including 1936's The Great Ziegfield).
