Space: 1999

Special effects supervisor Brian Johnson was asked to helm the special effects for Star Wars (1977), but his involvement with this series took priority. While helming the special effects for Alien (1979), Johnson was asked to take charge of the effects for Star Wars: Episode V - The Empire Strikes Back (1980), so he left the effects duties for Alien (1979) with his assistant on the project, Nick Allder, who had also been his main special effects assistant on this show, then moved on to work with the effects crew on "Empire". Johnson and Allder ended up sharing an Oscar for Special Effects for Alien (1979), then Johnson shared a Special Achievement Award for Special Visual Effects on Star Wars: Episode V - The Empire Strikes Back (1980). Johnson would later go on to helm the post-production visual effects on Aliens (1986), in which he would end up sharing a BAFTA Film Award.

Whenever anyone uses a commlock, a communications column in a hallway, or a comm terminal in a room they never set a channel for the call they make; they simply activate the device and it automatically connects to whomever the caller is looking to speak to.

During the first season, excerpts for each week's episode were incorporated into the opening credits, more specifically the "This Episode" section, which was something of a Gerry Anderson trademark.
