UPDATE 8/12 5:26pm
BOSTON (AP) â€” A bench in Boston has become a quiet memorial to Robin Williams, whose Academy Award-winning performance in "Good Will Hunting" was filmed in the city.
In the 1997 movie, Williams, playing an empathetic therapist, and his patient, a blue-collar genius played by Matt Damon, have a conversation on a bench in Boston's Public Garden.
Dozens of people quietly visited the bench Tuesday. Some left tributes â€” pinwheels, flowers, bottles of beer, a teddy bear, an autographed baseball.
Some used chalk to write messages on the walkway. Many were quotes from his performances: "It's not your fault," from "Good Will Hunting," and, "You ain't never had a friend like me," from "Aladdin."
Williams died Monday at his California home at age 63. Authorities say he hanged himself.

SAN RAFAEL, Calif. (AP) â€” Sheriff's officials say Robin Williams' personal assistant found him with a belt around his neck at his San Francisco Bay Area home.
Marin County Sheriff's Lt. Keith Boyd also said Tuesday that superficial cuts were found on Williams' wrist and a pocket knife was found nearby.
Toxicology results on whether Williams had any drugs or alcohol in his system are weeks away.
Sheriff's officials said Monday a preliminary investigation determined the cause of death was suicide due to asphyxia. Williams was 63 and had suffered for years from periodic bouts of substance abuse and depression.
Williams' press representative Mara Buxbaum said the actor had been battling severe depression recently. Just last month, Williams announced he was returning to a 12-step treatment program.
Coroner's officials say he was last seen alive at home around 10 p.m. Sunday.
