"The King's Speech" screenwriter David Seidler won the Academy Award for Writing (Original Screenplay) on Sunday, marking his first win and first nomination.

He beat Mike Leigh of "Another Year," Scott Silver, Paul Tamasy and Eric Johnson of "The Fighter," Christopher Nolan of "Inception" and Lisa Cholodenko and Stuart Blumberg of "The Kids Are All Right."

"My father always said to me, I would be a late bloomer," Seidler, 73, said in his acceptance speech. "I belive I am the oldest person to win this particular award. I hope that record is broken quickly and often."

"The King's Speech" stars Colin Firth as the stuttering UK monarch King George VI. Helena Bonham Carter plays Queen Elizabeth, his wife, and Geoffrey Rush portrays the king's speech therapist.

The movie was nominated for 12 Oscars, including ones for Firth, Bonham Carter and Rush, as well as Best Picture.

Hooper also directed the miniseries "John Adams" in 2008 and won an Emmy for directing the miniseries "Elizabeth I," which was released in 2005 and stars Helen Mirren and Hugh Dancy.

Seidler later told reporters backstage: "The fact that this film has come out has given so many people the courage to talk about their stuttering, and I've been flooded with the most wonderful e mails, phone calls, text messages from my fellow stutterers because I'm still a stutterer, all right."

" I know all the tricks - you don't hear it," he added. " I don't even have to think about it anymore, but I am still a stutterer. But to have these people tell me their personal stories, really moves me to tears."
