Nick Park has revealed he turned down Mark Hamill for a part in his latest Wallace And Gromit adventure.
The animator explained that he had a call from the Star Wars actor's agent but he never returned the call.
Instead he looked to the less 'Hollywood' cast of Coronation Street for people to do voiceovers for A Matter Of Loaf And Death.
"I'd already designed the character, and when I do that I'm always looking out for the person to play the part.
"I was driving back from Preston and heard Sally Lindsay on Radio Two on the Mark Radcliffe and Stuart Maconie show. I knew then that was her, I thought 'that's Piella'!" he said.
"Sally has a lot of fun in her voice, flamboyant almost, and I was also looking for someone who could be quite charming too, but with a slightly posh northern accent. Piella needed to at times sound well-to-do, and then at others sound quite gritty.
"I was just hoping they would say who it was because I'm not that familiar with Coronation Street, so didn't know who it was I was listening to," he continued.
"Thankfully, the DJs did and as soon as I got home, I went on the internet and looked her up, and knew she was perfect. That's how we do auditions at Aardman Animations!"
:: Wallace And Gromit: A Matter Of Loaf And Death screens on BBC One on Christmas Day. Their feature-length outing The Curse Of The Were-Rabbit gets its TV debut on the same day.
