Men in Black 3 (2012)

Of course the Men in Black can go back in time. You accepted those little mind-erase pen things, not to mention the idea of the existence of alien life that is central to this sci-fi franchise, but it's the time travel in Men in Black 3 (2012) that throws you off? Whatever. Anyway, yeah, so in this one Will Smith goes back to the swinging '60s to prevent the alien assassination of his pal Tommy Lee Jones, played here in his younger incarnation by Josh Brolin. The always out-of-this-world Alice Eve is sadly buttoned-up here as a young version of Emma Thompson's Agent O, but the real shooting star here is Pussycat Doll Nicole Scherzinger, who doesn't show her pussycat but puts more than a little jiggle in her step as the girlfriend of notorious space criminal Boris the Animal (Jemaine Clement). Nice moon rocks, Nicole!
