Mel Gibson's Cockney accent in new movie The Beaver was so convincing for early audiences they thought Jodie Foster had hired Londoner Michael Caine to dub his voice.
Director Foster tried to convince her leading man that his accent didn't have to be perfect for his role as a puppeteer in the movie - but Gibson insisted on getting it 100 per cent right.
She explains, "It was originally an English accent and we turned it into a Cockney accent. The beaver (puppet) is a working class south London scrapper.
"Some people thought it was Michael Caine or Ray Winstone or Bob Hoskins (talking as the beaver) and that Mel was lip syncing."
