I don't recall ever seeing Ellery Queen's Penthouse Mystery before. It's a 1941 mystery with Ralph Bellamy as Ellery Queen. The Ellery Queen novels are credited to Ellery Queen but it's really Frederic Dannay and Manfred Lee who pen them.
It's got a screenplay by Eric Taylor and the director is James P Hogan. Eric wrote around 50 movies in a career that started in 1936 and ended when he died in 1952. He was only 55 but before he croaked it he wrote several entertaining Universal horror films like The Black Cat, The Ghost Of Frankenstein, Phantom Of The Opera and Son Of Dracula. He wrote 6 more Ellery Queen movies, a couple of Dick Tracy movies and some starring The Crime Doctor. James started as a director in 1920 and he directed some of the Bulldog Drummond pictures and The Mad Ghoul. He died in 1943 at the age of 53.
Besides Ralph the movie stars Margaret Lindsay and Anna May Wong. The story centers around some smuggled or stolen jewelry. Plenty of good supporting cast: Charley Grapewin, Frank Albertson, Charles Lane, Russell Hicks, Tom Dugan and Mantan Moreland.
There's some lobby cards for the film.The Chinese jewels have been donated to help the starving people back home when they are sold in the US. Crooks are after them and there's lots of investigating as Ellery and his police Inspector father get on the case.
Not a great film but solid entertainment. Typical of the time. It gets a 5.4 on the IMDb and that's a good score for it even though only 66 people had voted before me. You can check it out in the link in the title above and see if you like it.
