Same prop, different films!
So I was watching KNIGHT OF 100 FACES (1960), the new HD print from a streaming service in Italy which I profiled recently. This scene stood out, for two reasons. One, the scene is often cut in other versions. I remembered not seeing this before. The second and more important reason, is the helmet or prop on the left. I recognized but I had to remember where I saw it before and then I knew where I saw it previously. It's from HERCULES UNCHAINED (1959; below, with Gabriele Antonini). It's so random.
