I'd recognize Sidney Toler's voice anywhere.
"Registered Nurse" is from 1934 and stars Bebe Daniels in her last film before moving to London, Lyle Talbot, John Halliday, Gordon Westcott, and the aforementioned Sidney Toler as a wrestling promoter.
Daniels is Sylvia Benton, unhappily married to Jim Benton (Westcott) who, on their way home from a party, crashes their car. We only see his unconscious body on the ground.
In the next scene, Sylvia seems alone and she's talking about going back into nursing, which she does. She turns out to be quite invaluable at the hospital and attracts the amorous attentions of both a surgeon (Talbot) and the head doctor (Halliday). Both want to marry her. What they don't know is that her husband is alive and locked up in an asylum.
Sylvia can't divorce Jim because the only grounds for divorce in New York was adultery.
Subplots concern the patients: a bordello madam (Irene Franklin), a cop (Ed Gargan), and Toler, whose character has a broken leg.
The limpid-eyed Daniels was a good actress with a beautiful speaking voice, and this cast acquits itself well in this Hollywood melodrama. I imagine during her time at Warners, Daniels and Kay Francis were probably up for some of the same roles.
After moving to England with her husband, Ben Lyon, she became a stage and radio star, and appeared in a few films with her husband. She remained married to Lyon until she died.
Daniels, who started acting as a child, came from an interesting family. She was related to DeForest Kelley of "Star Trek" fame, and her cousin, Lee DeForest, "the father of sound," was responsible for improving sound when it first hit the movies. Her daughter was a singer for Columbia Records, and her son a disc jockey.
Most fascinating of all, Al Capone was a fan, and when her jewels were stolen from a Chicago hotel, he got them back for her.
