Batman and Robin (1949)

Antisocial Prof. Hammil's Remote Control device, which enables the user to take over any motor vehicle within 50 miles (!), is stolen by The Wizard, black-hooded mastermind, and his gang. Batman and Robin (who drive about in a standard convertible) must prevent the Wizard from obtaining diamonds, needed as fuel for the device, and rescue magazine photographer Vicki Vale from periodic perils. Where is the Wizard's base, reached only by remote controlled submarine? Which of several suspicious characters hides beneath the Wizard's hood?
