The Cobra Strikes on AllMovie

Herbert Heyes, a largely unsung character actor who once played opposite Theda Bara in the silent days, is afforded one of his largest talking-picture assignments in The Cobra Strikes. Heyes is cast as Dr. Damon Cameron, who is murdered shortly after developing a revolutionary new medical instrument. The killer's motives seem obscure at first: what is certain is that several other murders take place before newspaper columnist Mike Kent (Richard Fraser) figures out what's what. A clue: Dr. Damon Cameron has a lookalike brother named Ted (also played by Herbert Heyes). Up-and-coming leading lady Leslie Brooks is hilariously miscast as a Russian novelist.
