The raunchy new comedy “Hot Tub Time Machine” isn’t exactly going for scientific accuracy: The key ingredient that allows the characters to journey through the space-time continuum turns out to be a can of Red Bull-style energy drink.
But time travel, no matter how seriously or comedically portrayed, never loses its power over our imaginations. It’s a device that allows us to break the most basic law of life: What’s done is done. Of course, sometimes that works, sometimes it doesn’t. Here are 10 time-travel movies, ranked from the most realistic to the most ridiculous — which isn’t necessarily a bad thing.
1. PRIMER (2004)
PLOT: In a Texas suburb, two engineers accidentally create a time-travel device. Their first thought: stock market! Their next thought: everything else.
TWO-TIMING: In this low-budget but highly complex film, the heroes create doubles of themselves in a temporary, temporal loop. In other words: mind-boggling.
