Kol Nidre
Background

Jolson played himself in a recreation of the Kol Nidre scene from The Jazz Singer (1927).
Reviews

Surefire...should score heavily in theatres of evey type. (Variety)
Verdict
In a fairly short but good cameo Jolson is a really minor player in this movie though he is the most entertaining thing about its second half in which it degenerates into melodrama. The first half has some entertaining restaging of early film comedy in this very fictionalised though thin veiled version of the story of the love affair between Mack Sennett and Mabel Normand.
