"Jaunting", the term used for teleporting in this series, comes from the novel "The Stars My Destination" (British title "Tyger Tyger") by Alfred Bester.
During the majority of the series, when the lab was located in the abandoned underground station, the control panel for the entrance was a prop that previously appeared in The Ark in Space: Part One (1975)). The prop was originally made for UFO (1970), and other panels and control desks from that series can occasionally be seen in both Doctor Who and The Tomorrow People.
The series was publicised as ITV's answer to the BBC's popular science-fiction series Doctor Who (1963), although it had an even lower budget and production values. An early publicity photograph included Nicholas Young, Peter Vaughan-Clarke, Sammie Winmill and Stephen Salmon pictured with Jon Pertwee, who was starring as the Third Doctor when The Tomorrow People made its debut.
According to interviews in the DVD commentary, Kenny was quickly written out of the series due to Stephen Salmon's poor dramatic ability and an inability to act in general, plus a lack of interest in acting. Salmon would frequently forget lines and spoke with a drawl, making him too difficult to understand by the other actors. For this reason, Kenny's character is seldom seen "in the action" after the pilot, with Kenny often guarding the lab or visiting his home during the bulk of the series.
Thames TV received letters from epileptics complaining that the opening sequence of the show was causing them to have seizures.
