Johansson loves being challenged

Los Angeles: Johansson, who would be seen alongside Matt Damon in `We Bought A Zoo` admitted she is "up for every kind of challenge" and likes to get stuck in when she takes on a new role.

"I think I`m up for every kind of challenge and I like to get down and dirty, yes. I really liked that aspect of Kelly (her character in the film), that she is a no-frills kind of girl, very grounded and practical, with that salt of the earth quality," quoted her as saying.

"That`s the body language I created for her too; she`s comfortable in her body and in her stance."

However, the 27-year-old star revealed he has developed a "hard shell" in order to cope with the constant "batterings" she has suffered in the film industry.

Johansson added: "I learned at a really young age that you have to have something of a hard shell to take some of the batterings that you get in this industry. We`re constantly rejected and scrutinised and it`s important to take a lot of it with a pinch of sale in order to be able to survive and press on."
