Rupert Grint was shocked to discover he could hold a tune while lending his voice to animated children's film, 'Postman Pat: The Movie'.
Rupert Grint was ''surprised'' to learn he can sing.
The 25-year-old actor shows off his musical talents in 'Postman Pat: The Movie' - in which he plays the titular character's talent show rival - and thought it would be ''a laugh'' to record his vocals, but didn't realise he could actually carry a tune well until he heard the finished track.
He explained to Dev on Radio 1: ''I was surprised, I thought it would be a laugh, I didn't take it too seriously but it came out alright, I was quite surprised when I heard it.''
However, Rupert - who shot to fame playing Ron Weasley in the 'Harry Potter' movie series - insists he has no intention of embarking on a music career.
Asked if he'll release an album, he said: ''I doubt it. It's hard, I don't know how people do it.''
Rupert was delighted to be a part of the 'Postman Pat' movie because he was such a fan of the original TV series when he was young.
He said: ''It's a very different kind of Pat to what I knew, he enters an 'X Factor'-style show and tries to pursue a career in music, and I play his rival.
''It's great, I'm proud to be a part of it because Postman Pat was one of my heroes when I was a kid.''
