In a world filled with black cats and Marilyn Monroes, we love to see a celebrity dress up for Halloween in a truly unique way. Case in point: Gwyneth Paltrow, whose costume this year was definitely outside the box鈥 in the best possible way.

Paltrow鈥檚 2017 Halloween costume, which she posted on her Instagram with a cheeky jack o鈥 lantern emoji, answers the frightening question we鈥檝e had for 22 years after seeing Se7en: WHAT鈥橲 IN THE BOX?

We鈥檙e not sure a more-than-two-decades-old movie can require a spoiler alert, but we鈥檒l just play it safe here.

*SPOILERS BELOW*

In the 1995 crime thriller SE7EN, Paltrow plays a woman named Tracy Mills, who is decapitated in a truly horrific way by Kevin Spacey鈥檚 evil character John Doe, who places her 鈥減retty head鈥 in a cardboard box, representing one of the seven deadly sins. In this case, Doe was envious of Tracy and her character鈥檚 husband David, played by the Goop founder鈥檚 then-boyfriend Brad Pitt, for their seemingly perfect marriage.

The climax of the film sees David begging and pleading to know what鈥檚 in the box and results with the audience (and David himself) horrified to learn what actually was in the box.

While we never get to see Tracy鈥檚 severed head in there, just the suggestion of it alone (and poor David鈥檚 anguish) was enough to make this scene an instant pop culture classic, still inspiring memes and GIFs to this day.

We love Paltrow鈥檚 costume idea because she鈥檚 the only one who could pull this one off so flawlessly. Perhaps next year we鈥檒l get her 鈥渄ying from bird flu鈥 in Contagion look? Dare to dream!

What do you think of Gwyneth鈥檚 SE7EN Halloween costume? Let us know @BritandCo.
