Zoe Saldana is "obsessed" with wolves.

The 'Colombiana' actress - who is known for her action-roles in movies including 'Avatar' and 'Star Trek' - loves analysing the social structures in the animal world, and believes the canines are far superior in intellect to their lion counterparts.

She said: "Sometimes I'm very ape-like, when I'm bouncing off the walls. I'm obsessed with wolves.

"From their social structures to their communities, I think we take more as a human species from wolves than lions. For me, The Lion is such a loser!

"In the Animal Kingdom, he sleeps all day, steals from his women and eats his cubs. But they are beautiful, because they have great hair. Like a rock star, I guess!"

Her love of animals may come from her upbringing, and Zoe confesses she was always interested in more masculine side of life.

She said: "I was always a very physical child. I was very hyper by nature. And my mom used to say about my sisters and I that we were very feminine tomboys."
