Visual effects master Ray Harryhausen, whose stop-motion wizardry - he made his models by hand and painstakingly shot them frame by frame to create some of the best-known animated sequences in cinema - became famous in movies from "One Million Years B.C." to "Sinbad", died Tuesday at age 92. 

Less well known, but famous among World War II buffs, was the "Why We Fight" series he made with Frank Capra for new recruits in the US Army, which also included work by Walt Disney. It was powerful stuff.  Capra, directed by G.C. Marshall, quite literally wanted new soldier to know why they were going to a foreign land and why it was right to do so.

Moviegoers remember him most for animating the seven skeletons who come to life in "Jason and the Argonauts", a sequence which took him three months to film, and for the Medusa who turned men to stone in "Clash Of The Titans".
