Batman - Series 1 - Death in Slow Motion

The Riddler turns moviemaker, capturing his criminal escapades on film. Robin is strapped on a conveyor belt in a lumberyard, about to be sawed in two as Riddler records the event. Batman comes to the rescue, but liberates a dressed dummy. Meanwhile, the Riddler is about to drop Robin from the ledge of a high building, similar to a well-known Harold Lloyd stunt.
