Ray Harryhausen was famous for his monster films. Some of the models he made for the films have been restored by a Dagenham man by the name of Alan Friswell.
There's a small exhibition of these models at the Valence House Museum in Dagenham, London. The exhibition is continuing to the end of June.
My brother recently went to the exhibition and took some photos of the models and I'm uploading them on to this topic. There are 9 photos, 2 from Jason and the Argonauts, 3 from Clash of the Titans (the original version) and 4 from The Valley of Gwangi.
