 Blue's escape from the control room was accomplished by throwing the puppet through a sheet of glass onto the backdrop of the control room set; though filmed at high speed, a gloved hand can be seen launching the puppet.The puppet that plays Colgan was a newly-made copy of revamp puppet 19, which had appeared in various supporting roles in "Captain Scarlet" and was making its debut as Sam Loover in "Joe 90" while "The Inquisition" was being filmed.The copy would also appear in the later series.
