An Edgar Wallace yarn was the basis for the uncharacteristic Warner Bros. melodrama Return of the Terror. Hoping to escape prosecution for a series of poison murders, Dr. Redmayne (John Halliday) feigns insanity at his trial. The audience knows that Redmayne is innocent, so when he escapes from the asylum and a new rash of murders breaks out, the good doctor is instantly scratched off the suspect list. But this time the audience has been led up the garden path, as proven in the over-the-top finale. The presence of Mary Astor and Frank McHugh in the cast reassures the audience that this is indeed a Warner production and not something out of Universal or Monogram. Return of the Terror is a remake of The Terror (1928), the studio's first all-talking horror film.
