Production starts on Fifty Shades
The actors - who play kinky billionaire Christian Grey and student Anastasia Steele in the movie adaptation of EL James' steamy novel - are working on the eagerly anticipated project in Vancouver.
Author James posted a picture of a film slate on Instagram with the word "Action" to mark the start of production. Producer Dana Brunetti re-tweeted the image, adding: "And we're off."
A photo on E! News gives fans their first look at Jamie as Christian, showing him on set in a grey suit jacket.
The film - which is being directed by Sam Taylor-Johnson - will be released in 2015, and there have been reports that there might actually be two versions, a toned down movie and one that is more explicit.
Brunetti recently told Collider that while the movie is likely to be R rated in the US (which means people under 17 can see it with an accompanying adult), there could also be an NC-17 version, which bars anyone under 17.
He said: " It'll be R, obviously it has to be R. This is just my opinion and this doesn't mean this is going to happen, but I always thought it would be really cool if we released the R version and then we had an NC-17 version that we released a few weeks later. So everybody could go and enjoy the R version, and then if they really wanted to see it again and get a little bit more gritty with it then have that NC-17 version out there as well. It'd be great for the studio too because they'd get a double dip on the box office...
"What we're kind of hearing from the fans is they want it dirty, they want it as close as possible [to the book]. We want to keep it elevated but also give the fans what they want."
