Brendan Gleeson had no idea of how to play his 'Pirates! In An Adventure With Scientists' character.

The 57-year-old Irish actor lends his voice to the part of The Pirate With Gout in the animated movie, but he admits his pretentious alter-ego was never supposed to be from the Emerald Isle.

He said: ''I had no notion of what to do with him at all. He wasn't meant to be Irish. If you feel there's an Irish stereotype thing going on, I think when you go into a cartoon, you can forget about all that sort of stuff.

''I like that he was quite pretentious. He's one of those blokes who is a mixture of total innocence and complete arrogance...''

Brendan jumped at the chance to work on the movie - which stars Salma Hayek, Jeremy Piven and Martin Freeman - devised by 'Wallace & Gromit' creators Aardman Animation because he is such a big fan of the animated short film series.

He added to ''It was a very interesting experience. 'Wallace & Gromit' is one of my all-time favourite creations, so, I didn't need to be asked twice, you know.''
