Moore surprised to secure Oscar nomination

Michael Moore is amazed his movie 'Sicko' has received an Academy Award nomination, because he thought he'd never be invited back after slamming US President George W. Bush onstage in 2003.

Moore outraged many with his controversial speech, which Oscars producers cut short, when picking up the Best Documentary award for Bowling For Columbine.

But the 53-year-old was pleased to hear his film about America's health care problems had picked up a Best Documentary Academy Award nomination on Tuesday.

He says: "I'm appreciative that they allowed me back in the building (Kodak Theatre).

"If I'm fortunate enough to stand on that stage again, I will be true to myself and very gracious and grateful for the acknowledgment, but I would start by finishing the last 10 seconds of the previous speech."

And the famously unstylish filmmaker adds: "I would thank my wardrobe designer and hair stylist."
