I didn't know it was made in 1977.I thought it was interesting that after the TCM presentation of Golden Voyage, Robert Osbourne made it a point to mention that it took Ray 2 years(!) to complete the stop motion animation for the movie. So it's possible that Eye of the Tiger was filmed 2 years earlier in 1975 but was finally finished in 1977. Perhaps someone who knows more about this than me can verify. Either way, Ray has an extraordinary amount of patience!
