On Wednesday, James, 50, revealed on Twitter that the movie had finally found its director.
"I'm delighted & thrilled to let you guys know that Sam Taylor-Johnson has agreed to direct the film of Fifty Shades of Grey," James Tweeted.
Taylor-Johnson, 46, – who is also professionally known as Sam Taylor-Wood – made her directorial debut in 2008 with Nowhere Boy, a film about John Lennon's childhood.
Her relationship with that film's 23-year-old star, Aaron Johnson, made headlines when the couple tied the knot in 2012 despite a 23-year age difference. She also directed a short film called Daydream which starred Snow White and the Huntsman director Rupert Sanders's ex-wife, Liberty Ross.
As far as who will play Shades's leading roles, Alex Pettyfer has reportedly shot an audition scene, while Emma Watson denied rumors she'd been cast as the stunning but impressionable Anatasia Steele.
