Beyonce may have given a glimpse of the upcoming trailer for the film version of E.L. James' novel "Fifty Shades of Grey." The singer posted a 15-second clip on her Instagram account with skirts, fingers, someone opening a door, and a remix of Crazy in Love with heavy breathing, possibly hinting at her involvement with the soundtrack of the film.

It also featured two unidentified actors who are possibly the main characters Christian Grey and Anastasia Steele portrayed by Jamie Dornan and Dakota Johnson, respectively. The man's face was not shown on camera, but he was seen staring out an office window. Meanwhile, the woman was only shown from the waist down, seated, with someone else's hand pulling her skirt.

The film's first full trailer is not set to debut until Thursday, but Beyonce's post has given an idea of what to expect in the 15-second clip. The Twitter page for the upcoming film, as well as Rita Ora's Twitter account, also posted the teaser. However, all of them remained rather silent with other details, except for the hashtag #fiftyshades.

Rita Ora will be portraying the role of Mia Grey in the upcoming film, while other members of the cast include Jennifer Ehle, Max Martini, Luke Grimes and Eloise Mumford, among others.

It is not the first time Beyonce has shown involvement in the "Fifty Shades" soundtrack as she was also rumored to have had a hand in the soundtrack last March when her song "Haunted" was also heard in clips shown at a trade show for the film industry, Today Entertainment reported.

According to IMDB, Sam Taylor-Johnson's movie version of British novelist E.L. James' book is set to be released in cinemas on February 13, 2015 in the United States. "Fifty Shades of Grey" is the first book in the erotica romance novel trilogy published in 2011.
