“He’s seriously charismatic. He has a gravitational field around him. I had to say to him at the beginning, in all my prosthetics, ‘I have to tell you I’m a little bit star struck and it might take me five minutes’.
“And he was like ‘I got you man. Don’t worry. Don’t worry.’ He was really, really sweet with me.
“There were lots of those moments. I was surrounded by all these famous people. And working with them.. so there was a lot to take in.”
Wilson has previously appeared in a number of big budget productions including Dodger, House of the Dragon and Under Salt Marsh.
He is soon to appear in the BBC’s California Avenue, and science fiction series Bladerunner 2099.
He said his friends call him “Welsh Sam”.
“I think it’ll take me some time to re-acclimatise to the fact that people are watching stuff that I’m in.
“Because it wasn’t very long ago I was doing pub theatre stuff… which I love too.”
Masters of The Universe, starring Idris Elba as Man-At-Arms, Nicholas Galitzine as He-Man, Camila Mendes as Teela, Alison Brie as Evil-Lyn and Jared Leto as Skeletor, was released in the UK on Friday 5 June.
