"Fifty Shades of Grey" movie cast is finally confirmed - and did Jamie Dornan and Dakota Johnson get into costume as Christian Grey and Anastasia Steele for the "Fifty Shades of Grey" movie? Author E.L. James posted a photo on her Twitter that possibly reveals cast members Jamie Dornan and Dakota Johnson as Christian Grey and Anastasia Steele.

"Guess who..." Author EL James tweeted Friday alongside a photo, which features the feet of a man and woman across from each other. The man's feet is in suede shoes, the woman's is in grey flats.

She followed this up with another photo of what looks like the same pairs of feet, but this time in different shoes: the man is in very fancy leather shoes, and the woman's feet are in beat-up sneakers.

While E.L. James didn't confirm anything, this looks a lot like Jamie Dornan and Dakota Johnson meeting E.L. James for the first time, and then donning shoes appropriate to their respective characters on "Fifty Shades of Grey." It seems reasonable to speculate that Christian would wear shiny leather shoes, while Ana would wear dirty Converse.

Fans immediately guessed the unidentified pairs of feet belonged to the the future Christian Grey and Anastasia Steele, IB Times reports.

"Oh my!!! Christian and Ana!!" wrote the Spanish "Fifty Shades" fan site 50 Sombras Spain, IB Times reports.

"Mister Grey and you! or Ana!" said user Cami Guzman Soto.

According to one fan, Twitter user Jane Ozera, the female in the image is Johnson. "It is Jamie and Dakota," said the "Fifty Shades" fan, adding, "I can see Dakota tattoo on her feet."

According to the Hollywood Reporter, the "Fifty Shades of Grey" film is still currently on schedule to be released on its original premiere date, August 1, 2014, despite the casting shake-up, IB Times reports. However, filming reportedly has been pushed back, and is set to begin in Vancouver in early December.

According to a report from The Wrap, the first trailer for the highly-anticipated "Fifty Shades of Grey" movie is rumored to be premiere during the 2014 Super Bowl in February, IB Times reports.
