For the lead star of a blockbuster trilogy commanding millions of fans and even more box office dollars, Jennifer Lawrence is remarkably self-deprecating.

Rather than dwell on the success of Hunger Games: Catching Fire - the second instalment in the hugely popular film franchise - the Oscar-winning actress is still busy cringing over that fall at the Academy Awards earlier this year, as she collected her best actress award for Silver Linings Playbook.

"There really was no magical recipe for falling flat on your face in front of the entire world and then forgetting to thank Harvey Weinstein [whose company produced Silver Linings Playbook] on stage," she says, speaking at a Hunger Games press conference this week. "I can’t say that a certain remedy or thought made me feel better. It’s just time went by and I could stop slapping myself every single time I thought about it.

"I can’t fall again. I can’t. I don’t have any plans to avoid future falls I’m just going to use sheer will power, maybe focus more when I’m walking. I do need some sort of high-heeled boot camp."
