Reviews
Seeing Big Boy is the nearest a modern audience could come to experiencing Jolson at his greatest. (Michael Freedland)
Verdict
The only film record of Jolson playing Gus his stock blackface character from his Winter Garden days Big Boy isn't a great film but Al definitely seems more comfortable in blackface. The fact he has the make-up on for most of the movie means this one hasn't been revived much if ever since its release, a pity.
