The Boy from Space (1971– )
- new educational footage in between the story sections;
- broadcast for the first time in color (although filmed in colour, most UK schools in the 70s had black and white TVs so was broadcast as such throughout it's 70s run);
- new opening titles with a theme song added;
- a new scene at the start of episode one featuring Sylvestra Le Touzel and Stephen Garlick reprising their roles as Helen and Dan (now as adults) reminiscing about their adventure as children - and their flashback begins the story (this version was also told in past tense, while the 1971 version was present).
