Mirren was 'outraged' when she heard her friend Russell Brand had been arrested at an airport in Los Angeles over a scuffle with a photographer, calling his detention 'outrageous' and 'unfair'.
Russell Brand was questioned by cops and charged with battery following an alleged altercation as he walked through Los Angeles International Airport (LAX) in September 2010.
Brand maintained he was defending his now-wife Katy Perry from an over-zealous snapper and the charge was later dropped.
Dame Helen Mirren, who worked with Brand on "The Tempest" and new movie "Arthur", admits she was "so angry" when she received news of her pal's arrest and was adamant he couldn't have done anything wrong as he is so "nice".
She tells Britain's Stylist magazine, "Russell was consistently nice (during the "Arthur" shoot). He was amazing. And then he pushed this one photographer... and I could not believe they arrested (him). I was outraged...
"I was so angry, it was outrageous. So unfair... Finally he's got a moment's peace to go off with (his) fiancee. B**tards. How dare they?"
