Yes, this is another public domain B movie from the 30s. This one probably has an even lower budget than usual. But unusually enough, despite being about performers, it not a series of stage acts weakly tied together by some irrelevant plot.
Instead it’s got a pretty weak plot with some stage acts intertwined. It’s a totally different thing!
I mean, it’s a real movie, but with some good stage bits here and there, and with some very appealing music.
The acting isn’t like scintillating and it’s all pretty routine (I mean, the plot is about a beleaguered actor putting on a show (an all-black Othello (I think; it’s difficult to say) in this case) while being chased by mobsters), but it’s enjoyable enough.
