Burt Lancaster, who starred in more than 60 movies, collapsed Friday and was rushed to a hospital, where he was in serious condition, officials said.

Lancaster, 77, was taken by ambulance to the emergency room of Los Alamitos Medical Center, nursing supervisor Lindy Beck said."He is listed in serious condition. We have not yet diagnosed a specific problem," Beck said. "He will be admitted to the intensive care unit."

Lancaster was visiting a friend at John Douglas French Center for Alzheimer's disease when he became short of breath, said Cheryl Hunter, a nurse at the center. He collapsed in a chair and called for help, Hunter said.

"He was heading toward the dining room . . . downstairs and he started wobbling a little bit," she said. "We called 911 right away."

Lancaster agent Ben Benjamin said: "We have no comment at this time. There is nothing we can say."

The veteran actor is best known for his lead roles in the movies "Elmer Gantry," for which he won an Oscar, and "Atlantic City."

The one-time circus acrobat has starred in such films as "The Killers," "Brute Force," "All My Sons," "Come Back, Little Sheba," "From Here to Eternity," "The Rainmaker," "Judgment at Nuremberg" and "Local Hero."

More recently, he has appeared in the films "Field of Dreams," "Local Hero" and "Rocket Gibraltar." His television credits include "Voyage of Terror."

Lancaster was released from the film "The Old Gringo" in 1988 because of frail health.
