Classic UK sixties comedy/satire as a small fictional European country accidentally creates anti-gravity fuel and along with the Americans and Russians a race is on to be the first to land on the Moon.
While most would characterise this as a gentle comedy and indeed its an all star comedic cast with Margaret Rutherford, Terry Thomas and Bernard Cribbins, however the script does have its moments such as when the American and Russian scientists accidentally reveal their Third Reich origins or the hype of the British watch worn by the astronaut played by Cribbins.
Though I remember watching this a kid on Saturday afternoons as an alternative to the horse racing on BBC2, I had only realised it was a Dick Lester film later and its amazing to think that just 7 years later via the couple of Beatles films he created The Bedsitting Room, a work of deranged genius.
