A trailer for the new Fifty Shades of Grey movie has taken the internet by storm, gaining more than two million views in the space of a few months.
What many viewers don't realise however, is that the three-minute video is a fan-made spoof.
The trailer - hosted on Youtube - shows Northern Ireland actor Jamie Dornan along with co-star Dakota Johnson in what appears to be footage from the steamy adaptaion of EL James' hit novel.
Closer inspection of the hit trailer, posted by user Ovskura Dama, shows that footage of the two stars has been spliced together using previous movies and television advertisements.
Also included are shots from an erotic film interspersed with a Hugo Boss advertisement starring Ryan Reynolds and footage of an Audi car.
The first official Fifty Shades Of Grey trailer was premiered at CinemaCon in Las Vegas this week.
"Nobody outside the studio has seen a frame of footage," Universal Pictures chairman Donna Langley said.
And fans of EL James' bestselling 'mummy porn' novel might not care about seeing one either if the focus remains on romance rather than erotica.
The trailer included a brief glimpse of a whip, a shot of Dakota Johnson wearing a blindfold, and Dornan's sexy billionaire character Christian Grey confessing to Johnson as Anastasia Steele, the young college student he seduces: "My tastes are very singular."
"Hearts and flowers – that's not who I am," adds Dornan's Grey.
Movie website The Wrap reported the footage was "surprisingly tame", and was more concerned with the romance between Grey and Steele than S&M kinkyness.
The Los Angeles Times said the nature of the event could have been the reason for the tame material.
"It's of course possible some of that footage was of the toned-down sort thanks to the CinemaCon crowd, which can be a more buttoned-up group," it said.
Langley, who introduced the clips, admitted the task of bringing the book to life on screen was "daunting".
She heaped praise on her stars, calling them "brave, bold actors", and promised their chemistry will give audiences "the next iconic screen romance".
"While the movie promises to be filled with all kinds of taboo carnal relations, what was shown in the clips was very PG-rated (they didn't even mention the word 'sex'). Of course, there was plenty of innuendo and suggestion of Christian Grey's habits behind locked doors, but none of it was explicitly shown."
