Hurd Hatfield plays the title role as Dorian Gray, in the only film role of note in his career. There is able support from the underrated Donna Reed, and as usual a great showing by a young Angela Lansbury as a songbird in an East End dive.
Of course there is the ever outstanding George Sanders, who as usual elevates the film. A good summary from IMDB is below.
Handsome, young, but morally corrupt Dorian Gray has his portrait made. As the years pass, he does not age, but evidence of his sins are apparent in his portrait, which grows uglier with each transgression. He keeps it safely hidden in the attic. But his mysterious behavior and ageless appearance begin to attract suspicion.
