This movie was in English, probably from the 60s. I saw it in mid to late 70s as a child. I remember it being from caveman era and the people worshipped the sun. They drew sun on their foreheads. I remember the main girl was beautiful and didn’t look like the rest of the girls there. I can’t remember if she was not originally from that land or how she got there. But the cavemen I think we’re going to offer her to the god but the love interest character who I think was one of the cavemen but looked handsome compared to the rest saves her. not sure if I remember the plot accurately but the yellow (I think) Sun on the foreheads was what stuck with me.
