In Walk, Don't Walk, three people stand on a street corner. They are waiting for the signal of the street sign to change so they can cross. Do they look like people you know? They might. They are cast from real people. Notice their clothing, hair and shoes. Even the buttons and wrinkles are there. They look real but they are all white. Look at the street sign. The electric lights flash red and green. Have you seen a street sign like this? The sign is not a casting. It is real.
