Is there a (mad) doctor in the house? "Yes!" shrieks Doctor X, fi lmed in rare two-strip Technicolor. An eminent scientist aims to solve a murder spree by re-creating the crimes in a lab fi lled with all the dials, gizmos, bubbling beakers and crackling electrostatic charges essential to the genre. Lionel Atwill is Doctor Xavier, pre-King Kong scream queen Fay Wray is a distressed damsel, and Lee Tracy snaps newshound patter, all under the direction of renowned Michael Curtiz.
