Forrest Gump Transcript
EXT. A SAVANNAH STREET - DAY - 1981
A feather floats through the air.
The falling feather. A city, Savannah, is revealed in the background.
The feather floats down toward the city below.
The feather drops down toward the street below, as people walk past and
cars drive by, and nearly lands on a man's shoulder. He walks across the
street, causing the feather to be whisked back on its journey.
The feather floats above a stopped car. The car drives off right as the
feather floats down toward the street.
The feather floats under a passing car, then is sent flying back up in
the air.
A MAN sits on a bus bench. The feather floats above the ground and
finally lands on the man's mud-soaked shoe. The man reached down and
picks up the feather.
His name is FORREST GUMP. He looks at the feather oddly, moves aside a
box of chocolates from an old suitcase, then opens the case. Inside the
old suitcase are an assortment of clothes, a ping-pong paddle, toothpaste
and other personal items. Forrest pulls out a book titled "Curious
George," then places the feather inside the book. Forrest closes the
suitcase. Something in his eyes reveals that Forrest may not be all
there. Forrest looks right as the sound of an arriving bus is heard.
