Irishman Andrew Scott who plays the part of arch-villain Jim Moriarty in the BBC drama Sherlock Holmes, caught up with RTÉ 2fm's Ryan Tubridy to chat about the second series of the hit TV show.

Speaking about his role as a criminal mastermind and all-round baddie Scott said: "I have had an absolute blast. He is an extraordinary character to play. I was delighted to be given the opportunity to do it".

"It’s a really brilliantly written show. We are all so thrilled with how successful it has become."

When asked how he prepared for the role, the Dublin native said: "It was very important to me that I didn’t do a bad version of what someone else has done. I didn’t look at a huge amount of previous incarnations of Moriarty or indeed of any villains. I wanted to draw on what was scary within me, and make my character original."

He added: "Sometimes when you tie things up in a bow, it can seem a little considered to your audience."

A third series of Sherlock Holmes has been commissioned but in last night's climax Moriarty shot himself in the head. However knowing the twists and turns of this series that doesn't necessarily rule out a return for the Irish actor.

Scott is currently in Manchester working on a four-part TV series with Christopher Eccleston. He recently completed a film entitled The Scapegoat based on a Daphne du Maurier novel.
