The movie spins an interesting tale, and Sherman's directing and acting are top rate as usual, but you can't help but be struck by the fact that the script gives Silas Brenton no redeeming or humanizing characteristics at all, and that Brenton has no exit strategy from the fraud he is perpetrating and has got to know will eventually be discovered. He starts out doing "false face lifts" - not really doing anything - and telling patients they need to wait six months to see results, but then moves on to bigger and more dangerous surgeries he's got to know he's unqualified to perform. I'll let you track down a copy of this film and see how it plays out.
Berton Churchill plays Dr. J.B. Parker, Brenton's partner as "consulting physician" who, unlike Brenton, seems to know when Brenton has carried things too far. Lila Lee plays Silas' girlfriend from New York who is torn between loving this guy and knowing that he has to be stopped and brought to justice.
Look out for the interesting nightclub scene towards the middle of the film. The M.C. comes out and introduces celebrities in the audience. Among them is Ken Maynard, a western star of the 20's and 30's who, ironically, suffered a professional implosion of his own making just like the fictional Dr. Brenton.
