SYDNEY, Australia (AP) _ Mel Gibson donated $640,000 to the Sydney school where he studied acting, officials said Wednesday.

Gibson, one of Hollywood's top box office draws, grew up in Australia after his parents migrated from the United States.

The donation to the National Institute of Dramatic Art was announced at a function to celebrate the school's 40th birthday.

Gibson studied acting for three years at school beginning in 1977.

The Daily Telegraph newspaper reported the money would help the college build a new theater, film and television studio and performance arts library.

Gibson, whose latest blow-'em-up flick, ``Payback,'' is a major hit, lives in Los Angeles.
