The scene I remember seeing was in color and looked to be made around the 80’s or 90’s. It was a medieval setting but I think there was some sort of time travel involved.  The heroine was captured by the villain and he put her in this room filled with his harem. The ladies start saying how they are also princesses on the certain days of the week that they sleep with the villain. The other memorable thing was that the heroine poured the wax of a hot candle into a goblet for the villain to drink. She did the classic hold out a cup suspiciously so that they take the other one. The wax doesn’t really do anything but makes the villain chock up a little and get angry with her. I think all the while there’s a battle going on in the courtyard of the castle. At the end there is a bunch of lighting that the hero has to have strike his sword (I think).
