The much talked about book is finally heading to the big screen. And after a month of delayed filming, 'Fifty Shades of Grey' production is now starting to roll the camera for Jamie Dornan and Dakota Johnson, the lead actors for E. L. James' best-selling steamy novel.

According to the Huffington Post, filming for 'Fifty Shades of Grey' has started just this weekend in Vancouver since the movie adaptation is set to hit theaters on Feb. 13, 2015.

Author E. L. James is reportedly working side-by-side with director Sam Taylor-Johnson on the 'Fifty Shades of Grey' movie. James even posted a photo on her Instagram account Sunday to tease fans about the progress on the film. James' post instantly received a lot of likes and many fans even expressed their excitement for the film.

It can be noted that the delay in the start date of the filming was due to Charlie Hunnam's exit from the lead role of Christian Grey. Fortunately, the producers found a replacement in 'Once Upon A Time' star Jamie Dornan right away. Meanwhile, '21 Jump Street' star Dakota Johnson has been sharing to the public her preparations for the role as Anastasia Steele ever since she was picked to portray it.
