It’s worth remembering that nobody intended for Give Or Take A Million to be the end of the Thunderbirds television series. It would be wrong to judge it against other series finales because for the production team, this was not considered to be the end of Thunderbirds. It looked as though A.P. Films, now Century 21, had found their winning format and would continue making Thunderbirds for as long as there was a demand for it. Hopes were also high for the Thunderbirds Are Go movie to launch International Rescue into a string of adventures on the big screen. Although the movie failed to perform at the box office, there was still hope for further success, and so Thunderbird 6 was commissioned. But for the television series, the plug was pulled very suddenly by Lew Grade when the sale of the series to the American networks fell through – a result of him raising the price too high. But that high value sale was necessary for the production of Thunderbirds to continue being financial viable to Grade, it was something he had counted on – and without it, the most expensive television series in the UK at that time simply could not continue. And so, rather unluckily, the last episode we have been left with is this Christmas special – a merry escapade for a Christmas Day evening, but when weighed against the rest of the series, is lacking some pretty vital components.
