Two Thunderbirds feature films were released in the 1960s alongside the TV episodes.

Between 1980 and 1982, three compilation films were produced – for which a number of the original episodes were re-edited and truncated – and released on home VHS by PolyGram and subsidiary Channel 5 Video.

Century 21 Records, a Century 21 subsidiary established in September 1965, released 19 Thunderbirds audio dramas in the form of 7-inch, 33 RPM, vinyl EP "mini-albums" between 1965 and 1967. Sixteen are adapted from original TV episode soundtracks, cut to a running time of 21 minutes and including additional narration from a member of the original voice cast performing in character; the other three are new adventures.
