(Can you tell I'm on Spring Break?)
Déjà Vu (
Wikipedia,
IMDB) starring Denzel Washington with Val Kilmer as a major supporting character is what I would call a stealth Sci-Fi movie. Based upon what I recalled of the trailers and such, I was expecting the movie to be a Denzel Washington action drama, with touches of thriller and some sort of supernatural/ghosts/New-Agey crap. And then they slammed us with Kilmer explaining about Einstein-Rosen bridges and wormholes while Washington throws chairs at monitors and yells something to the effect of "stop talking science and tell me the truth!" Had me in a giggling fit and rewinding to hear it another two times as I totally don't picture Kilmer as a scientist-type, and Washington strikes me as more intelligent and likely to understand time travel.
They did a decent job of explaining the physics of wormholes, and also the sci-fi aspects of time travel, causality, and alternate universes. I like how they resolved his death in the end, and explained a bunch of the small inexplicable things (though I was expecting they would all be explained via messages, not bodily travel). The chase scene is entirely gratuitous, and I admit I zoned out a bit during it, but it doesn't detract overall.
If you're a fan of Sci-Fi, action, and/or Denzel Washington, this one's a must-see. I'm a fan of all of the above, so I definitely enjoyed it.
