Finally, we've come to the smoking-hot excuse to watch Denzel Washington be smoking hot (in several ways) in a movie of time travel: "Deja Vu."

The Tony Scott-directed, Denzel Washington-starring movie is a consummate action vehicle that actually does pretty well with time travel. It's also the movie that originally inspired "So You Created a Wormhole: The Time Traveler's Guide to Time Travel." After watching it way back in 2006 (or whenever), it was "Deja Vu" that led us to look into trying to explain time travel stories.

As it turns out, though, "Deja Vu" is pretty solid. And Denzel rules.
