The Oscar-winning actress splits her time between her native U.K. and Los Angeles, and admits she is growing tired of the British tendency to criticise and mock famous figures.
Mirren reveals she likes to get away from the ""small-minded"" attitude by spending time in the U.S., where people are more positive.
She tells Woman and Home magazine, ""The one thing I really don't mind escaping when I go away is the alacrity with which Brits like to put people down.
""It's nice to escape from that. Sometimes there's a narrowness of vision in the UK - maybe it's partly an island mentality.
""In America, they are less cynical and maybe a bit more naive. Brits are somehow more critical and mealy-mouthed. And there can be a sense of small-minded jealousy sometimes.
""It's not my overriding feeling about Britain at all, but occasionally there is that element in the media and society, and it's corrosive and dangerous.""
