Scenes from THE GIANT OF MARATHON (1959)

These matte paintings in the movie are all excellent. And there are more of these. The screenshots are taken from a print in HD and they look amazing. Mario Bava is credited for cinematography and visual effects. They hold up beautifully. It's odd because these effects are much better than the ones in HERCULES IN THE HAUNTED WORLD (1961), also by Bava.

This shot is great but I don't know what to make of it. It looks like the battle at the end of HERCULES UNCHAINED (1959). The actor was added in with green screen.
