No. 9 Halloween Video: Katy Perry, ‘E.T.’
The E.T. in Katy Perry's hit song has little to do with the Reese's Pieces-lovin' alien. But Kanye West does play a "big-headed astronaut" who floats through the sky in a glowing orb while spitting a couple of verses. Mostly, though, the sci-fi video stars a sex-hungry space girl (played by Perry, of course) drifting through a post-apocalyptic wasteland looking for love, or something like it, while grainy footage of animals getting it on whirs by. It's E.T.'s "phone home" plea as an interstellar booty call.
