December 29, 1967 –
Star Trek first aired The Trouble with Tribbles episode – arguably one of their most famous episodes – on this date.
To create the one tribble moving on its own, the prop supervisor bought a battery powered toy dog and stripped it down to the mechanical works. Once recovered with fur including the toy legs, the prop moved on camera along the railing on the Enterprise bridge without wires or external assistance. The toy was so noisy all the dialogue in the scene had to be looped with ADR (re-recorded after shooting).
