Fifty Shades Of Grey fans have been given a tantalising glimpse of the movie in the first official trailer to be released online.

Universal has unveiled the trailer for the big screen adaptation of EL James' hit erotic novel starring Northern-Irish hunk Jamie Dornan as sexy billionaire Christian Grey and Melanie Griffith's daughter Dakota Johnson as Anastasia Steele, the young college student he seduces, and introduces to the world of sadomasochism.

The two minutes and 25 second clip opens with a nervous Anastasia going to Christian's office to interview him, but he seems more interested in her.

A voiceover hears her later describing him to her friend as "intense" and "intimidating".

But then their romance begins to unfold, with the couple kissing passionately in a lift to the soundtrack of an exclusive new recording of Crazy In Love by Beyonce.

But then the love story takes a dark twist as Christian is heard telling Anastasia "I don't do romance... my tastes are very singular", as a topless Dornan strides over to a drawer and takes out a blindfold.

Anastasia asks, "Enlighten me then," and the trailer ends with Christian unlocking his dungeon and a titillating montage of shots involving whips, robes and blindfolds.

The final shot is of Anastasia, blindfolded, naked and tied to a bed, in the throes of ecstasy.

The trailer teases: "This Valentine's Day... the worldwide phenomenon... comes to life."

The movie, directed by Nowhere Boy's Sam Taylor-Johnson , is released on February 14, 2015.
