Reviews

This is Jolson's picture...the rest is also ran. (Variety)

 

Jolson's singing is something for the memory book. (New York Times)
Verdict
Al is plainly playing himself in this movie and doing a great job of it. Great to see the real Jolson projecting some of the style that ignited the stage of the Winter Garden. Of course the main focus of the movie is meant to be Power and Faye but the Jolson songs are what make it memorable.
