Turn to the dictionary definition of “over-achiever” and you may well find yourself looking at a picture of Dylan Alcott.

Not content with his stellar sporting record in both wheelchair tennis and basketball, a burgeoning TV and radio career, running a music festival and heading up his own consultancy and advocacy organisations, Alcott is now determined to crack the world of theatre with his stage debut in The Rocky Horror Show this week.

“I’m a f---er for opportunity,” says the 33-year-old. “To be honest I can’t believe it and I’m very, very grateful for it.

“I’ve had a burning desire to have a crack at acting for two reasons. One, I love sharing stories and challenging myself, but also I want greater representation on our screens, on our stages of people with disability. It’s always been something that I’ve been passionate about and I thought rather than talk about it, let’s give it a crack.”

Alcott will play The Narrator in the classic Richard O’Brien show, which this year celebrates its 50th birthday, alongside veteran performer Jason Donovan.

And while this is Alcott’s first time on stage, he can already list “actor” on his impressive resume, after his role last year in the streaming show, Bump, with Claudia Karvan.

“That was a good test because I was like, ‘If I don’t like it, I won’t do it. But also, if I’m really, really crap, I won’t do it’,” he says. “But I got a good enough response.”

Alcott is well-used to the spotlight and there will be more excitement than trepidation when he hits the Theatre Royal stage.

“Of course there will be nerves, but I also get on a stage three times a week and do a lot of keynote presenting,” he says. “So in that instance, I’m used to the stage.”
