A towering figure in the history and evolution of motion-picture special effects, Ray Harryhausen created some of the most memorable creatures ever to stalk, slither and sail across movie screens in the 1950s, 1960s and 1970s. A tutelage under effects pioneers George Pal and Willis O'Brien inspired Harryhausen's own stop-motion animation, which gave vivid life to aliens and monsters of myth in such iconic fantasy and science fiction films as "The Beast from 20,000 Fathoms" (1953), "The 7th Voyage of Sinbad" (1958), "One Million Years B.C." (1966) and "Clash of the Titans" (1981). Harryhausen's imaginative work would later serve as inspiration for generations of filmmakers, including Steven Spielberg, Peter Jackson, Tim Burton, James Cameron and countless others, all of whom paid tribute to him in their own fantasy film exploits. Before his death in May 2013, he fittingly racked up various honors for his undeniable creativity and vision.
