This is gonna be huge. 

The first promo for the big screen adaptation for Fifty Shades of Grey has just been released, and seems to be loyal to its source material if the first trailer is anything to go by. 

Starring Dakota Johnson as cental character Anastasia Steele, this should see her and her co-star Jamie Dornan's popularity rise to stratospheric levels. 

The film is directed by  Sam Taylor-Johnson
