The lovely Lena Headey is a favorite with just about everyone here at Cinematical -- click on her tag and you'll see many love letters devoted to her films both past and upcoming. Now she's adding a new credit to her resume, as Headey will be taking the director's chair for her film Kill Drug.

Formerly titled Retribution, it's a project Headey has been attached to for some time ... and when you want to get a movie done, you tackle it yourself. Starring Headey, the formidable Charlotte Rampling, and Jason Flemyng, it centers on an underground group of Longon vigilantes. Headey will star as Sally, a woman recruited into by its founder ... who just happens to be her mother, Sue, who murdered her abusive husband back in the 1970s. However, Sally discovers that all is not as it seems, and that absolute power corrupts absolutely ... and probably that working with your mother is a really bad idea.

"My ambition to direct has been fuelled over the last fifteen years, by working alongside great directors. It has also been my film education," Headey told Empire. "Kill Drug is smart, articulate, compelling, sexy, fun, dark, deeply poignant and not afraid to laugh at itself. Above all it is a gripping and compelling journey, a study of humanity's darkest flaws and purest innocence."

Headey has been slowly making her mark as one kickass chick in films and television -- and it's pretty darn cool that she's going to join the rare, elusive breed of female directors. Hopefully Kill Drug will be the first of many on her resume.
