Resurrection of the Daleks - season 21 - 1984
“Up on the second floor two ‘stunt’ Daleks are awaiting their
cue. Unlike their brethren, these Daleks are not made from wood
and fibre-glass — they are elaborate constructions of expanded
polyurethane foam, cast from the same moulds as the live
Daleks. They are much lighter in weight and hollow inside. Into
each of these hollows has been packed a quantity of explosive
material. A tiny, thin wire emerging from the base will, on cue,
detonate these charges. This is why the casings are of foam —
though the charge is estimated not to be too powerful, it will
explode. There must be no danger of flying material likely to
cause harm, especially since Peter Davison and Janet Fielding
will be involved in this scene, with literally a bird’s eye view of
the event.
Carefully, the Visual Effects Designer, Peter Wragg, checks
the length of wire that will detonate the explosives; it is long
enough to reach almost to the ground from the loading bay door.
At the end of the wire is a pin connected to the charges inside the
Dalek. When the wire goes taut it will pull the pin out, allowing
two sprung connectors to come together. And when that hap-
pens, Bang!!!”
