This first of the two Waxwork horror films has secondary worlds, but no time travel. Move along to Waxwork II.

After the flaming climax at the end of Waxwork (which had no time travel that I could see), Mark and Sarah (a different actress) crawl home only to be followed by a disembodied hand that (before being garbage-disposaled into tiny pieces) hacks Sarah’s nearly evil stepfather to death. Nobody at Sarah’s subsequent trial for murder believes that story, so after listening to a movie of dead Patrick Macnee, they escape into a series of bad horror movie remakes from Frankenstein to Aliens.

Of course, all these movies are set in different times, but is there any actual time travel? The final scene gives a definitive answer, when Sarah meets James Westborn, after the verdict of her trial.
