Synopsis by Hal Erickson
Petrus is a tailor-made vehicle for lantern-jawed French farceur Fernandel. The star plays a naïve photographer who falls in love with nightclub dancer Simone Simon. Though she travels in a more sophisticated crowd, Fernandel never gives up his dream that someday the girl will be his. And sure enough, thanks to a series of plot convolutions that would be ridiculous anywhere else but on the Silver Screen, Simon is finally won over by the stumbling shutterbug. Petrus was co-adapted by director Marc Allegret from the play by Marcel Achard.
