Fans of stop-motion animation know this movie as a great achievement. This was special effects genius Ray Harryhausen's last movie and he demonstrated what an expert he truly was. Many people scoff at this movie's effects because they seem crude coming after the jaw-dropping "Star Wars". I choose to appreciate them because they seem like a tribute to the great stop-motion films of the past like "King Kong" "Jason and the Argonauts" the "Sinbad" movies and others. There are many impressive creature creations. Medusa the Kraken the giant scorpions; they all deserve consideration as the greatest entries in the stop-motion Hall of Fame. The scene with Perseus hunting for the head of Medusa remains tense and suspenseful. Medusa slithers around her lair hunting for Perseus the silence broken only by her flying arrows and rattling tail. The Kraken is also impressive a giant beast from the sea summoned by Zeus and released by underwater god Poseidon. Where "Clash of the Titans" falls apart is the frustrating scenes with the gods who bicker and place curses on the favorite mortals of each of them. I also continue to wonder why Poseidon has to pull a lever to release the Kraken? If the Kraken is so powerful how can it be caged? If Zeus is really all-powerful why doesn't he just retrieve the magic invisible helmet for Perseus after he loses it? Why does the blood of Medusa only turn into giant scorpions when her head is poked with a big fork? But putting all of these questions aside "Clash of the Titans" is a fun last hurrah for one of stop-motion animation's greats.
