"Night World" has a dynamic start and lots of promising pre-code elements, which, however, don't quite jell; maybe the problem is the lack of a really compelling plot. But it has a natural, unaffected performance by Mae Clarke, one early Busby Berkeley dance number (with lightly dressed girls) that's a clear sign of things to come from him, and a hard-hitting finale. If you like this film, you must watch "Wonder Bar" from 1934 - it's similar, and even better. **1/2 out of 4.
