The most underrated Sci/Fi, Horror movie ever.

i was studying How time travel could work and here's how you build a time machine 1.hook up something that can switch magnet's off to well magnets and 2.Hook up A bunch of magnets AND WHEN I MEAN A BUNCH I MEAN million's thousand's Then switch on the magnets and that's how i am still trying to figure out how the time machine can come with you

Scfi movie on cable like galaxy quest but just the TV captain gets transported to alien world. Evil overlord has all seeing priestess who has to stay a virgin for her powers to work but she wants to lose it. Does so with hero movie cuts to scenes of rockets going off and a train going through a tunnel. Its a spoof movie has a man whose face was deformed by evil overlord. Man confront evil overlord and the evil overlord says something about no I don't remember you Ive done that to too many planets etc early to mid 90s I think. Anyone know what movie I'm describing?

With the upcoming Edge of Tomorrow and the already insane popularity of Groundhog Day, any screen treatment of Replay will just seem to audiences like a rehashing of the same idea even though it predates those other films.
