So it turns out Gwyneth Paltrow is actually really, really, REALLY funny.
SPOILER ALERT: If you've never seen the movie "Se7en" just stop reading now.
The usually serious actress just blew everyone else's Halloween costume out of the water going as ... Gwyneth Paltrow's head in a box.
The costume is a brilliant homage to Gwyneth's character in the 1995 thriller, whose decapitated head ends up in a box at the end of the movie.
We're sorry we misjudged you, Gwen.
