TRENTON, N.J.?Dudley Moore, the cuddly little Englishman who portrayed a lovably forlorn drunk in “Arthur,” died Wednesday of complications from a rare and incurable brain disorder. He was 66.

The comic actor died at a friend’s home in Plainfield of pneumonia stemming from progressive supranuclear palsy, which is similar to Parkinson’s disease and affects one of every 100,000 people.

Before breaking into the movies, the 5-foot-2 1/2-inch classically trained pianist found success in comedy revues in London and on Broadway as part of a legendary British troupe.

His film career peaked in 1981 with the smash “Arthur,” in which he played a rich drunk who falls for Liza Minnelli. He was nominated for a best actor Oscar.

“He had a little-boy-lost quality about him, which women loved, and there was always something slightly forlorn about Dudley,” said Michael Parkinson, a British talk-show host.
