Pinewood Studios coincided with that of Bugsy Malone, in which Lev played the role of Dandy Dan. The Masters' dog, Spring, was played by Byrne's pet, called Bones. Filming Filming began in July 1975 and ended that September. The production was budgeted at £105,000 (about £ in ). Principal photography was conducted at Pinewood Studios and completed in ten days, while the special effects shooting, which took place at Bray Studios, ran for six weeks. The special was directed by Charles Crichton, who had directed eight episodes of Space: 1999. Other members of the crew – including effects director Brian Johnson, editor David Lane and cinematographer Frank Watts – had also worked on the series. As Anderson's regular composer Barry Gray had other commitments, newcomer Derek Wadsworth was contracted to produce the theme and incidental music (the latter in collaboration with Steve Coe). Wadsworth would later be appointed composer for the second series of Space: 1999, replacing Gray. In the absence of Bob Bell and Keith Wilson, who were working on The New Avengers and Star Maidens, Anderson's business partner Reg Hill assumed the role of production designer. The Altares interiors were the first sets that Hill had designed for Anderson since the production of Fireball XL5 more than a decade earlier. They were built from parts of the Ultra Probe set originally made for the Space: 1999 episode "Dragon's Domain", along with design elements from other episodes. Other sets and props were also recycled from the earlier series. The scale models of Altares were designed and built by uncredited model-maker Martin Bower, who took inspiration from the various spaceships that had appeared in Space: 1999 and was initially under the impression that his work was to appear in that series. A model was used for long shots; close-ups used a larger, version, which was fitted with a powerful light for the photon drive as well as freon gas-powered jets to simulate exhaust. The Space Station Delta model was adapted from the SS Daria model that had appeared in "Mission of the Darians". Some of props that were newly made for the special would re-appear in Space: 1999s second series. Similar to the title sequences of Anderson's earlier productions, The Day After Tomorrow begins with a fast-paced montage of action shots from later in the episode, giving a preview of the story to follow.
