He is the greatest- yes GREATEST- film animator who ever lived... his stop action work from the 60's still has more life and artistry than 99% of the CGI work out there.
The Guardian put it best..."After that it was impossible not to consider how different cinema would be without such an inspiring figure. Just going by the list of acolytes who contributed to the evening alone, we'd have no Star Wars, no Terminator, no Toy Story, no Pan's Labyrinth, no Edward Scissorhands, no Jaws, no Shawshank Redemption, no Wallace and certainly no Gromit. Those are just the collateral damage, without Harryhausen there would be no Jason And The Argonauts, no 7th Voyage Of Sinbad and no 20 Million Miles To Earth. That's not a world I'd want to live in. It wouldn't be much fun."
