Spooks star Rupert Penry-Jones is "thrilled" by his guest role in series three of Stan Lee's Lucky Man opposite James Nesbitt.
He will play master manipulator Samuel Blake, nemesis to Co Antrim star Nesbitt's detective inspector Harry Clayton, in next year's third instalment of the action-packed crime drama.
Viewers will see him attempt to acquire the Lucky bracelets for his own ambitions.
Penry-Jones, known as Adam Carter in Spooks and Clive Reader in Silk, said: "I'm thrilled to be joining the cast of Lucky Man for an exciting third series."
Nesbitt said: "Stan Lee's Lucky Man is such an exciting series to make and the scripts for this season are brilliant.
"Harry Clayton's luck is running out, which throws up some interesting storylines. And also takes him, and me, to Hong Kong - the perfect setting for Stan Lee mayhem!"
