Academy Award-winning screenwriter Donald E. Stewart died April 28 in Los Angeles of lung cancer. He was 69.

He struck Oscar gold in 1982 for penning the Jack Lemmon/Sissy Spacek starrer “Missing.” Other credits include “The Hunt for Red October,” “Patriot Games” and “Clear and Present Danger.” Most recently, in 1997, Stewart co-wrote the telepic “Dead Silence,” starring James Garner.

He started his writing career as a journalist, first reporting for the Detroit Times and later co-founding the Competition Press, which eventually evolved into the current Autoweek.

In 1960, Stewart left reporting to work as an ad copywriter and creative exec at top New York agencies including J. Walter Thompson, Y&R and BBD&O. He moved to Hollywood in 1975 to give screenwriting a try — and obviously succeeded.

Stewart is survived by his wife, two sons, a daughter and grandchildren.

Donations in his memory can be made to the American Cancer Society.
