Lead actors Jamie Dornan and Dakota Johnson were filmed walking out of an upmarket office building on set in Vancouver, Canada on Sunday.

Former underwear model Dornan, 24, plays handsome billionaire with a dark side Christian Grey, while newcomer Johnson has been cast as Anastasia Steele, the young college student besotted by his charisma.

The pictures, taken by Splash, show the stars filming the key scene in which Christian presents Ana with a sexual contract detailing his demands for their bedroom antics. Ana is seen clutching a brown envelope in the newly released images.

Directed by Sam Taylor Wood, the night shoot photos depict Ana getting into a car after stopping to give Christian a kiss on the cheek before leaving.

Dornan and Johnson’s co-stars, including “How We Do” singer Rita Ora, Eloise Mumford and Marcia Gay Harden, have yet to be spotted on set.

Fifty Shades of Grey is scheduled for US release on Valentine’s Day weekend 2015. Production was pushed back a month following the re-casting of Christian Grey when original actor Charlie Hunnam resigned due to scheduling and family reasons.

The trilogy has sold over 70 million copies worldwide to date, making it one of the fastest-selling book series of all time.
