Transition montage (Fast, Cheap & Out of Control):

From the robot scientist back to the lion trainer in ten or eleven shots:

From main post: Notice the string of surreal visual associations (Buñuelian -- as in "Un Chien Andalou") that take us from the robot scientist back to the lion trainer for the first time: b&w shot of crawling robot (seen in opening credits); b&w shot of man and boy from the old serial; shot of volcano erupting from serial; shot of man and boy continuing to walk from serial; b&w shot of people arriving in big circus tent, its pointed peak echoing the shape of the volcano; color shot of naked mole rats underground; color shot of elephants at the circus; color fast-motion tracking shot of topiary gardener, head on (you'll catch a glimpse of an elephant topiary animal in the background); color fast-motion tracking shot of a clown dressed like an animal (pig?) from behind; b&w shot of a clown carrying a traffic light across one of the circus rings -- whip pan to the animal/clowns from the previous shot now coming (full-circle) toward the camera; vintage b&w shot of lion trainer Clyde Beatty in action...
