Lake Placid - Building the 30-Foot Animatronic Crocodile Puppet

See how Lake Placid’s 30-foot animatronic crocodile puppet came to life behind the scenes at Stan Winston Studio, featuring a water-resistant urethane skin and a moving head, tail & snapping jaws that functioned underwater using waterproofed hydraulics.

The Making of Lake Placid’s 30-Foot Animatronic Crocodile

Lake Placid is a Steve Miner film about the search for a man-eating, thirty-foot crocodile in a lake in Maine.

Designing a Massive Underwater Puppet

Stan Winston and his crew realized Lake Placid’s crocodile as a full-size animatronic puppet — complete with moving head and tail and snapping jaws — that would function underwater.

Creating a Fully Functional Animatronic for Water

The crocodile was mechanized through hydraulics, which, as had been learned on previous projects, worked fairly well in a water environment, as long as they were protected in waterproof housings and surrounded by a water-resistant skin.

Testing the Full-size Crocodile Puppet in Water

To test the crocodile puppet’s efficacy in water, the SWS crew took it up to Castaic Lake, in the Los Angeles National Forest, prior to painting it, and dropped it in. “That thing actually swam,” Landon remarked. “Its head left/right and tail left/right functionalities were enough to make it propel itself through the water.” To gain greater swimming speed during filming, the crocodile was most often attached to a wire and pulled through the water by boat.

“We went into this show with the full knowledge that water always wins,” said Richard Landon, who led the mechanical crocodile design team. “That has become my personal motto: Water Always Wins. Water will always break something. Water is the universal solvent. Superglue breaks down in it. Urethane breaks down in it. Paint breaks down in it. Water is a nightmare — and we were in it for a full six months on this show.”
