BEVERLY HILLS, Calif. (AP) -- Actor Glenn Ford, who played strong, thoughtful protagonists in films such as "The Blackboard Jungle," "Gilda" and "The Big Heat," died Wednesday, police said. He was 90.

Paramedics called to Ford's home just before 4 p.m. found Ford dead, police Sgt. Terry Nutall said, reading a prepared statement. "They do not suspect foul play," he said.

Ford suffered a series of strokes in the 1990s.

Failing health forced him to skip a 90th birthday tribute on May 1 at Hollywood's historic Grauman's Egyptian Theatre. But he did send greetings via videotape, adding, "I wish I were up and around, but I'm doing the best that I can.... There's so much I have to be grateful for."

At the event, Shirley Jones, who co-starred with him in the comedy "The Courtship of Eddie's Father," called Ford "one of the cornerstones of our industry, and there aren't many left."

Ford appeared in scores of films during his 53-year Hollywood career. The Film Encyclopedia, a reference book, lists 85 films from 1939 to 1991.

He was cast usually as the handsome tough, but his acting talents ranged from romance to comedy. His more famous credits include "Superman," "Gilda," "The Sheepman," "The Gazebo," "Pocketful of Miracles" and "Don't Go Near the Water."
