Like many celebrities before her, one of the characters she's played on the big screen. Only in this case, Paltrow's creative choice is also a huge, horrifying spoiler.

For the uninitiated (and those looking for spoilers for a 22-year-old movie), "Seven" follows the exploits of a serial killer (Kevin Spacey) who patterns his murders after the seven deadly sins. A detective, played by Brad Pitt, tracks the killer, who taunts him by leaving horrific, gruesome clues; his final act is to present Pitt's character with a box, which contains the severed head of his wife, Tracy, played by Paltrow. (We told you it was horrific.)

In a darkly comic choice, Paltrow decided to embody Pitt's famous line "What's in the box?" this year, and posed alongside her boyfriend, Brad Falchuck, who dressed as the killer. (Kind of poor timing for either one of them to be associated with Spacey, unfortunately.)

We're not sure the actress can ever top this costume, but we're eager to see what she comes up with next year all the same.
