As a previous commentator put it so well, Larry Parks is better at playing Jolson than Jolson is! It's a fact. Watching him perform as Jolson is infinitely more pleasurable than watching the man himself--and if you've seen any of Jolson's own films you'll acknowledge the truth in my statement. Thank God Larry Parks was chosen to play him--his lip synch job is amazing. When those pure rich tones emanate from his mouth the movie goes into high gear. A dazzling number of songs sung in Jolson's inimitable style makes this a real treasure for fans of nostalgia. It's no wonder this was one of the most popular films of 1946. Glossy production values, a great cast, a script that whitewashes the true Jolson character but still has enough bearing on reality to make it an interesting bio. A total pleasure from beginning to end--again, mainly because Larry Parks was at the right place at the right time. Definitely one of the best musical biographies of all time...and fortunately, the sequel is not far behind it. See 'Jolson Sings Again' and you'll see what I mean.
