I do not remember too much about the plot of the movie just remember one scene. I watched this some time in late 80s.
Hercules and his friend are captured. They are made to find blind folded with daggers or shorts while trying to balance themselves on the beam that is above some sort of spikes. They start to fight but during the fight they realize that they know each other, they take off the blindfolds.
I remember Hercules character being strong but not anything spectacular.
At this time I can't even remember if it was black and white or in color. Movie had a vibe of movies like Cleopatra or Spartacus and other movies about Roman or Greek empires with all men walking in tunics and main heroes being very well built.
