Design

Mechanical effects supervisor George Gibbs said the film was the most difficult one of his career.^[11] He visited a museum to negotiate renting a small French World War I tank, but decided he wanted to make one.^[12] The tank was based on the Tank Mark VIII, which was 36 feet (11 m) long and weighed 28 short tons (25 t). Gibbs built the tank over the framework of a 28-short-ton (25 t) excavator and added 7-short-ton (6.4 t) tracks that were driven by two automatic hydraulic pumps, each connected to a Range Rover V8 engine. Gibbs built the tank from steel rather than aluminum or fiberglass because it would allow the realistically suspensionless vehicle to endure the rocky surfaces. Unlike its historical counterpart, which had only the two side guns, the tank had a turret gun added as well. It took four months to build and was transported to Almería on a Short Belfast plane and then a low loader truck.^[11]
