Ricky Wilson has always been a massive Harry Potter fan and he was delighted when movie producers asked him to be in the penultimate part of the hit screen franchise.
The Kaiser Chiefs frontman was asked to be in the 2010 film, Harry Potter and the Deathly Hallows Part One, which saw Harry and his pals Ron and Hermione leave Hogwarts and embark on a hunt for horcruxes in a bid to destroy Lord Voldemort.
Ricky was supposed to be part of an all-star band who played at the wedding of Bill Weasley and Fleur Delacour in the opening stages of the film, but things turned out quite differently...
Now, a decade later and the singer has finally spilled the beans on how he came to work alongside stars like Daniel Radcliffe and Emma Watson - and how he even stole another actor's part!
"I got a call a long time before the film came out," said Ricky. "There was a wedding in the film and they wanted a band to play at the ceremony. They wanted me and Alison from Goldfrapp to be the singers, with Matt Bellamy from Muse on guitar.
"I thought 'This is brilliant!' and I was so excited, but a few months later another call came and they'd decided they weren't going to do that, they were going to do CGI instruments floating around instead. I was gutted so I asked if there was any chance I can just go and be in the film anyway. They said I could so I went along and dressed up as a wizard for a few days."
Rather than the wedding scene, Ricky appeared in a shot during Harry, Ron and Hermione's break-in at the Ministry of Magic and can be seen leaning against a wall in a purple suit as the trio exit a lift.
"They did the scene and it was brilliant," he explains."Then they said, 'Oh, you're in the shot. So you're gonna have to come for the next five days so we can film from different angles.' So I spent five days leaning against a wall wearing a purple suit."
Yet there is another twist in the tale. Ricky plays an unnamed character but was falsely credited with playing another actor's part.
"That's the other thing," he says "I'm credited as playing the part of Dirk Cresswell. But that's not me! That's another guy who actually had a part. But then at some point, someone said, 'Oh, that's Ricky Wilson'. Even the Lego Minifigure says it's me. It's not me. I was just an extra and I've totally stolen some poor guy's career. Even now, if I'm walking out of a gig or something and someone shows me a picture of the actor that played that part, I'll sign it. But it's not me!"
If it wasn't Ricky Wilson, who played Dirk Cresswell in the Harry Potter movies?
This remains a mystery to this day, but whoever the poor chap is probably isn't a Kaiser Chiefs fan!
Ricky Wilson on working with Daniel Radcliffe...
Yet while the actor who played Dirk Cresswell probably wasn't best pleased, Ricky has fond memories of meeting Daniel Radcliffe and the rest of the film's stars on set...
"Daniel and the rest of the guys were fantastic," he says. "I was an extra, but none of the other extras knew I was famous and they didn't like the fact that I was getting treated slightly differently. I was allowed to sit in Daniel's chair in breaks.
"They were looking at me thinking 'Who is this guy?' I'd be having lunch with the stars and they'd be in a big tent in the cold and they didn't know why. It was bothering them because there's a hierarchy when you're an extra and you don't mess with it!"
"The production team even let me make my own wand," he continues. "I had a tour of the studio and I went to the props department. The whole thing was a fantastic experience!"
