The buzzed-about "Fifty Shades of Grey" film officially has a screenwriter: Kelly Marcel, a British writer who is best known for her work on Fox's Terra Nova series.

To celebrate this week's movie news, we've compiled all the must-have items for a "Fifty Shades of Grey" Halloween costume — whether you plan to dress as author E.L. James or the story's protagonist, Anastasia Steele. Hoping your plus-one will sport a Christian Grey costume? We've found the best accessories for that outfit, too.

There are plenty of sexy toys, of course, but diehard fans will recognize some of our more obscure picks, too: Anastasia's plum dress, red sheets as an ode to the red room of pain, Christian's favorite champagne, and a toy helicopter to represent their transportation of choice.
