Sienna Guillory has joined the cast of Luther.
The British actress, who has guest-starred on such American hits as Covert Affairs and CSI, will come on board Season 3 of the BBC drama as Mary Day, a vintage clothes shop employee who will serve as a love interest for Idris Elba's title character.
Said Guillory in a statement:
"You realize why Luther is so good when you read Neil Cross’s scripts, and then you meet Idris and understand what 'untamed' means. There is no other set I'd rather be on, and I love the disastrous fun of being Mary Day, the right girl in the wrong place."
As teased in an official network press release, look for John Luther to be "back under intense pressure," on Season 3, "with two conflicting crimes to investigate and a ruthless ex-copper determined to bring him down. Luther’s life is his job; that is until love crosses his path and offers him a chance of happiness."
Adds Elba: "I want to thank the fans for waiting so patiently for the new season. We’re thrilled to deliver it to you. Here comes John!"
