The only scene I really remember is a monk is sitting on hill with woman and man/knight walks up, there are two cups on the tree stump and the monk makes guy choose a specific cup. I know it's a knight or medieval movie.

I think you might be looking for the Princess Bride - great movie! Is this the scene?:
