Goin' To Heaven on a Mule

Background
After the disappointment of Hallelujah I'm a Bum (1933) Al was back at Warner Brothers but only one of many stars in this film. It wasn't a happy shoot as the rest of the cast including Kay Francis and Dick Powell thought Al was hogging scenes. Jolson also had a personality clash with Ricardo Cortez. Jack Warner though was so impressed by the rushes he signed Al for three more pictures.
Reviews

Romance, flash, dash,colour, songs,star studded talent and almost every known requisite to ensure sturdy attention and attendance. (Variety)  

Verdict
Not Jolson's greatest hour on film, he is swamped here and only has a couple of songs one of which is the Goin' To Heaven On a Mule sequence which is dated and boring. The best thing about Wonder Bar is Busby Berkeley's routine to Don't Say Goodnight.
