Hercules (Steve Reeves) trying to secretly enter Thebes via a river in HERCULES UNCHAINED (1959)
Whenever I see scenes like this one in old movies, I always wonder how polluted the water was and how bad it might have been for the actors. The story's setting might take place thousands of years ago, when most rivers were clean, but the film itself was shot in the 1950s, when regulations were lax. Reeves is almost always working in and around some river / sea setting in practically all his films. He must have been weary about this.
