(Cover) - EN Showbiz - Naomie Harris is "back on the couch" after over-exerting herself while shooting Skyfall.

The stunning actress has joined the cast of the James Bond franchise as Eve. She worked hard to get in shape for the action sequences she had to shoot although the physical exertion didn't come easily to her.

"Those action scenes were tough, it's hard work! You have to do all the acting on top of running around, carrying a loaded weapon, scenery falling down..." she told a UK radio station.

"I did [get into the exercise] during the movie, now I'm back on the couch."

The 36-year-old star has never been a fan of spending hours in the gym. However, she didn't realise how unfit she was until she fell ill during training for the latest 007 film.

"I bunked off PE, I hated exercise. It took me three weeks to get unto it. I threw up a few times, seriously," she laughed.

"It is the most challenging thing I've ever done... I absolutely loved it. I'm a fan of Bond. I grew up watching them." (C) Cover Media
