to stunt co-ordinator Tom Lucy, a cross between Western, martial arts, and Bourne. The building used to film searching for one of the canisters was a British Gas building in Cardiff. The scene with Jack falling off the building was performed by Curtis Rivers, John Barrowman's stunt double. Though Rivers made the stunt to make Jack "look good", Barrowman had to lie on a box over green screen. Marsters and Barrowman were used for filming close to the roof's edge. Visual effects and animatronics While the most noticeable visual effect was John's entrance through the Rift, The Mill also made inconspicuous visual effects, such as extending the number of crates at the docks. The visual effect used for the Rift was redesigned for the second series, due to a decision among the visual effects team at The Mill that separate manifestations of the Rift appear different — in this case, orange and gold was used to make the Rift appear "warmer and more magical". The Mill also made three different types of holograms. The projection from Jack's wriststrap device was coloured blue to match earlier appearances, John's wriststrap projected a flashier, full colour image due to specifications in the script, and the golden hue in the projection of John's ex-lover was based on the prop. The blowfish in the opening scene was intended by executive producer Russell T Davies to be "like Finding Nemo, but evil" and the producer of the episode, Richard Stokes, wanted the designs to be as flamboyant as "the lionfish in The Spy Who Loved Me". The first designs of the costume were visibly different from the final design; the first designs were more fish-like than humanoid. After a humanoid design was approved by the production team, Millennium FX, who previously created the prosthetics for Doctor Who and the first series of Torchwood, immediately sculpted the costume to Paul Kasey's dimensions. Two versions of the mask were created; one was animatronic, which included mechanical fins, and one was used for the stunt where the blowfish was shot in the head.
