Speaking to RTÉ TEN ahead of his role as Shrek in the musical, Dean Chisnall, revealed that he's "so excited" to bring the show to Dublin.

He said: "I am so excited. I have so much love for this show and this character. I did it in London originally and bringing it on tour is just brilliant. It's very rare these days to bring an entire West End production on tour. It's just such an exciting thing to be part of.

"It will be our first time in Dublin. I've never been to Ireland. It's going to be a whole new experience. I hope, and we think, it's going to go big there. I'm looking forward to it."

We, of course, had to ask Dean about the process involved in becoming the green ogre.

He added: "The process is quite extraordinary. The make-up takes two hours alone. I'm in the chair at about 3.30pm to 4pm for a 7pm performance. It's a big commitment but it's worth it because no expense is spared. It's all in the detail. I can't complain. It's all part of my job and I love it."
