 No attempt was made to create the Batmobile, so a black 1939 Cadillac Series 61 convertible was used, chauffeured by Alfred when Bruce Wayne and Dick Grayson were either in their civilian or Batman and Robin identities.It is driven "top-up" when it is the Batmobile, and "top-down" when it is Bruce Wayne's car.While many serials made changes as part of their adaptation, to the extent that they were "often 'improved' almost out of recognition", Batman "fared better than most and changes were minor".
