The Mad Doctor Of Market Street (1942)

Starring Una Merkel, Lionel Atwill, Claire Dodd, Nat Pendleton, Richard Davies
Directed by Joseph H. Lewis
(actor & director credits courtesy IMDB.com)

After a failed experiment that ends in murder, a reckless scientist flees the police aboard a doomed cruise ship, and is stranded with his fellow passengers on a South Seas island. 

An entertaining horror-adventure film from Universal, with Atwill in fine form as his typical sinister man of science, the picture also features a wonderful supporting cast, playing an amiable lot of characters stranded with Atwill.  Merkel and Pendleton in particular lighten up the proceedings with their usual comedic shtick.  It may not be a great film, but it's more than representative of the fun potboilers Universal was putting out for the better part of the decade.

The Case Of The Velvet Claws (1936)

Starring Warren William, Claire Dodd, Winifred Shaw, Gordon Elliott, Joseph King
Directed by William Clemens
(actor & director credits courtesy IMDB.com)

Attorney Perry Mason must put off his honeymoon with Della Street when a woman demands his help at gunpoint.

A lesser entry in the Perry Mason film series without the pacing and energy of other installments, this isn't a bad movie, and fans of William should enjoy it, but I found it rather routine.  Dodd seems to go from loving Mason to wanting to end the marriage somewhat arbitrarily, and although a plot twist with Mason's client trying to implicate him in a murder is interesting, the supporting players don't have much of an opportunity to flesh out their roles.
