Jim Carrey is America`s favourite `Uncle Sam`

London: Canada-born Hollywood star Jim Carrey is most wanted to be cast as `Uncle Sam` in a movie about the fictional symbol of all things American, according to a new poll.

In an online poll to mark Independence Day in the US on Sunday, visitors were asked who they would choose to play the bearded and top hat wearing character, Female First online reported.

And nearly half chose the 48-year-old funnyman, who gained US citizenship in 2004.

Forty-six per cent voted for Carrey, 26 per cent for Robert De Niro, with comedian Chris Rock a close third with 25 per cent.

Uncle Sam first materialised in the early 19th century as a symbol of America and its government and has since appeared in numerous books and cartoons.
