Nothing has been overlooked on detail in providing a heavy doctor touch, plus sets of an intricate laboratory and surgical apparatus which in itself is sometimes a little gruesome. They have been well done with the color lending much to underscore the tension.
A lot of Doctor X is routine, including the love interest and the conventional murder mystery technique and background [from a play by Howard W. Comstock and Allen C. Miller] but it does not become tedious.
Lionel Atwill overshadows everyone as the head of a surgical research laboratory, under the roof of which several maniacal murders have been committed.
Atwill’s is a much stronger part than that given newspaper reporter Lee Tracy. It’s also much better written and carries a great deal more conviction. As the daughter of the surgical lab’s boss, Fay Wray quickly becomes involved with the reporter who finally saves her life from the big killer.
The tinting in Doctor X is at all times soft rather than strongly defined and after a time does not distract attention
