Jamie Dornan has been drafted in to play Christian Grey following Charlie Hunnam's sudden exit

Filming on Fifty Shades Of Grey will begin later than planned following the sudden exit of Charlie Hunnam and last-minute casting of Jamie Dornan.

Director Sam Taylor-Wood was due to start shooting early next month (November) but production will now begin around a month later on December 2, The Hollywood Reporter has confirmed. The film is currently set for release on August 1, 2014, which gives Taylor-Wood an ambitious eight-month turn-around time.

Sons Of Anarchy star Hunnam was originally hired to play sexually adventurous businessman Christian Grey but dropped out earlier this month (October) citing his “immersive TV schedule”. Northern Irish actor Dornan – best known for his roles in US fantasy series Once Upon A Time and BBC Two’s hit serial killer drama The Fall – has since been drafted in to replace him.

Dakota Johnson (pictured right) will co-star as Anastasia Steele, the college graduate who enters into an intense sexual relationship with the older and dominant Grey. Pride And Prejudice actress Jennifer Ehle and True Blood‘s Luke Grimes will appear in supporting roles.

Shooting will take place in Vancouver and Taylor-Wood is directing from a script Kelly Marcel (Saving Mr Banks, Terra Firma) has adapted from EL James‘s blockbuster erotic novel.
