I'm trying to find the title of a movie from around the 80's. The plot had an evil guy "rival scientist?" that went back to medieval times to kill off the ancestor of another scientist. The good scientist daughter is sent back with a guy and I think another girl to stop the evil scientist from killing her ancestor. They end up stopping him and they return to the future where the daughter is unhappy and goes back to medieval times to be with her true love. Hope someone remembers this movie and its title.

The movie is called Back to the Future. It has afew sequels... one of them is bound to be the medi-evil one. Haha but the title is Back to the future. It could be Back to the future 1, 2 or 3. Ummm the only other one that I can think of is Evil Dead.

It's not Back to the Future 1, 2 nor 3

It seemed to remind me of that. Okay well I tried haha . Let see you do better Ginani lol
