At the start of the week, the first preview for Fifty Shades of Grey landed online in a pretty unexpected place – Beyoncé’s Instagram. The footage teased the arrival of the full trailer today, and Focus and Universal have delivered, as promised.

Adapting E.L. James’ best-selling novel, the first in a trilogy, the film is dated for Valentine’s 2015, and I’m seriously wondering if birth rates will have a measurable rise when November 2015 rolls around.

Here’s the synopsis from the original novel:

As literature student Anastasia Steele interviews successful young entrepreneur Christian Grey for the student newspaper, she finds him attractive, enigmatic and intimidating. Convinced their meeting went badly, she tries to put Grey out of her mind – until he happens to turn up at the store where she works part-time. Ana, innocent and unworldly, is shocked to find herself desperate to get close to him. Unable to resist Ana’s quiet beauty, wit, and independent spirit, Grey admits he wants her, too – but on his own terms. Shocked yet thrilled by Grey’s erotic tastes, Ana hesitates. For all the trappings of success – his multinational businesses, his vast wealth, his loving family – Grey is a man tormented by demons and consumed by the need to control. When the couple embarks on a daring, passionately physical affair, Ana discovers Christian Grey’s secrets and explores her own dark desires. The first instalment in the Fifty Shades trilogy by E L James, 50 Shades of Grey is erotic, romantic and totally addictive.

Jamie Dornan and Dakota Johnson take centre stage as Christian Grey and Anastasia Steele, alongside Luke Grimes, Victor Rasuk, Jennifer Ehle, Max Martini, Marcia Gay Harden, Rita Ora, and Eloise Mumford, with a possible appearance from Aaron Taylor-Johnson, the director’s husband.

Sam Taylor-Johnson (Nowhere Boy) is directing from a script by Kelly Marcel (Saving Mr. Banks), with subsequent rewrites from Patrick Marber (Closer) and Mark Bomback (Dawn of the Planet of the Apes).

Fifty Shades of Grey will be released on February 13th, 2015, just in time for Valentine’s Day next year.
