Jake Morrison: To film the scene, having an insane amount of wind was the only way we could do that. We still built all the spaceships, but they’re basically all just wooden stand-ins. We did it all in the car park actually out the back of the studio, and just really asked our special effects brothers and sisters to just bring all of the wind, please. The point was, if you’re in an open-top car and it’s going 30 miles an hour, you’ve got to shout. So if these people are actually standing on the top of a spaceship going at Mach 4, fine they’re Gods, but at least their hair’s got to be doing something, you know?
