Special Effects wizard Carlo Rambaldi is most famous for creating E.T. (1982) along with his work on King Kong (1976), Alien (1979), Conan the Destroyer (1984), Dune (1984) & King Kong Lives (1986) among others. However the really neat stuff is all the work he did on tons of Italian films in the 60's and 70's including Mario Bava's Planet of the Vampires (1965) & Bay of Blood (1971) along with Bloody Pit of Horror (1966), A Lizard in a Woman's Skin (1971) and almost countless other horror, gaillo, peplum and sci/fi films (most times uncredited).
Here's a couple of my favorites - his nightmarish Medusa from Medusa vs. the Son of Hercules (1963), along with a huge sea monster from the same movie. I think the only way to get this movie is still this (which I only paid about $10.00 for at Big Lots years ago) box set. A big part of the fun of watching these is waiting for a Rambaldi creature to show up. Sadly he passed away on Aug.10 2012. He really deserves a giant hardcover book.
