I loved this. A rare colour feature from 1961, around the same time as THE TIME MACHINE, which is I think a British response to the monster movies from 1950s Hollywood, with classics such as THE BLOB, THEM and more,
I love dinosaur films and have watched a lot - and I can see this influence of this in both THE VALLEY OF GWANGI (1969) - which itself influenced Jurassic Park the film massively, esp the T-rex end scene but also others, as Spielberg has admitted - but also JURASSIC PARK 2, the movie. Ultimately all about the vanity of Man.
I thoroughly enjoyed it anyway. Though the model GORGO monster is hilarious, far too cute to be scary as well. I loved the scenes of London in 1960/1 too.
As ever, I research actors in these films. The boy is Vincent Winter who after being a child star worked as a production manager on such films as For Your Eyes Only (1981), Superman III (1983), Indiana Jones and the Temple of Doom (1984) and The Color Purple (1985). Sadly died of a heart attack aged 50.
4 stars. A great Friday Night fun film to laugh at and with!
