"Eve kicks ass. I'm loving it at the moment. I am such a pacifist, I never thought I would enjoy firing guns but, in the safety of the gun range and at a target board, it's so much fun," she said.
Naturally, this role probably calls for a lot of physical movement so she's preparing rigorously stating..."I'm doing gyrotonics (a fluid training style that blends movements of yoga, dance, gymnastics, tai chi and swimming on a machine) twice a week and I have a yoga teacher three times a week who also takes me jogging."
A table reading with co-stars Daniel Craig and Dame Judi Dench left her starstruck. "It was really intimidating but it was brilliant. I was thinking: 'What am I doing?' But was so thrilled at the same time."
Harris is aware that, despite being in high profile films such as Pirates of the Caribbean and Miami Vice, she's been pretty much under the radar publicly and actually likes it. "It's great I can be pretty anonymous. After the launch, my face was everywhere in the papers and on the news. I was worried. But, amazingly, I was still able to get on and off the bus and no one recognised me," she said.
Skyfall, directed by Sam Mendes, will be released November 2012.
