Fifty Shades of Grey movie is just weeks away from fans but new updates about the filming of the raunchy BDSM-themed movie have surfaced on the internet.

Jamie Dornan, who plays the character of the intimidating Christian Grey, has revealed that he tied up his penis in a small skin-coloured bag in order to avoid embarrassment while filming the graphic sex scenes.

"Your dignity is intact as much as it's all tucked away in a little flesh-colored bag," the Irish actor told GQ Magazine during an interview.

"As a guy you put all your essentials in a little bag and you tie it up like a little bag of grapes and it's tucked away. It's quite a peculiar thing to do every day."

The highly anticipated movie is an adaptation of E L James' erotic novel of the same name and stars Dakota Johnson as the naive college student Anastasia Steele, who is madly in love with the sexy billionaire entrepreneur Grey.

Recently, the movie received 'R' certification and rumours are abuzz that it will feature explicit sex scenes between the lead actors.

The erotic movie is about how Christian and Ana discover true love through each of their sexual encounters which involve the Dominant and Submissive relationship.

The former Calvin Klein model also spoke about his growing fan following and his fears of being murdered during the movie's premiere!

"I almost don't want to put this out there into the ether, but I fear I'll get murdered, like John Lennon, by one of those mad fans at the premiere... Because a lot of people are very angry that I'm playing this character. And I'm a father now, and a husband. I don't want to die yet."

The Sam Taylor-Johnson directed movie offers a sexy glimpse into the sadomasochistic world of the dashing and successful entrepreneur Christian, who is smitten by college student Ana. The movie will also feature Grey's famous 'red room of pain'.

Fifty Shades of Grey will premiere on 13 February, 2015.
