Pirates of the Caribbean and The Office star Mackenzie Crook guest stars in the first story as conman and thief Cedric, determined to take Merlin’s position as Arthur’s right-hand man.
He reveals: “I was a big fan of the first series of Merlin. I watched it with my son, Jude. He has met everyone from Johnny Depp to Al Pacino to Steven Spielberg – but he has never been more starstruck than when he met Colin.”
Other guest stars in this series include Sarah Parish as “a disgusting troll” masquerading as a beautiful lady, Adrian Lester, Charles Dance and the return of Heroes star Santiago Cabrera as Lancelot.
Colin comments: “We were all pretty excited when we heard about the guests that we’ve had coming in. Mackenzie is fantastic because his character starts off as this jewel thief trying to infiltrate his way into the castle. But something happens midway through that changes him completely.
“So he had to do two completely different characters in a way. Seeing him do that was literally freaky towards the end.”
Mackenzie remembers Bradley being a little nervous of him at first.
“For two days Bradley couldn’t open his mouth without putting his foot in it and saying something inappropriate: complimenting me on my performance in a film I had nothing to do with, bringing up spectacular failures in my career.
“But after larking around on set together we became firm friends.”
