The gorgeous `Tron` star would love to be revered for her acting skills but she understands that being successful in Hollywood is often dependent on looks although she is insistent she is no `dunce`.

She explained to The New York Times: "Trying to fight this industry`s tendency to celebrate the physical is a waste of time. So I`m happy to play that game. But I am also thirsty for input. I`m not a dunce whose only skill is knowing how to take a photograph, you know? And at the end of the day I think it makes me slightly less replaceable."

However, Olivia is not precious about her looks with `Cowboys & Aliens` director Jon Favreau revealing Olivia was determined to undertake as many of the stunts on set as she could including one where her character is pulled off her horse by a flying alien.

Of the sequence - where Olivia is taken off a speeding horse by a wire attached to a crane - he said: "Frankly, she put our stunt riders in a tough spot. Here was our ingenue, doing all of the scary stuff and making it look easy."
