this film rank with they save hitler brain a one of the most campy film of all time . the story and performance be laughably unbelievable . basically the scenario be this represent mengele ( peck ) clone hitler about 100 time and then kill all the clone adoptive father because hitler father die . and there something about a dog birthday . one of the few b movie by the otherwise great actor peck and olivier . the only interesting scene be at the end when olivier shake hand with a clone . worth watch only for camp value .
