Sorry, not much to go on.

This comes from a misdirected link in Kodi.

The movie starts with a man riding a horse in the desert. He comes to a set of rocks, and one stone door frame, poking out of the sand and walks towards them. He pulls out a map from his pocket and looks at it. He walks around a few of the stones and then goes towards the stone door frame and it becomes a portal. That is as far as it got. The man could be some sort of D&D type of character too.
