The first scene in which Douglas' mother appears, she is smoking a cigarette at the kitchen table. The cigarette is an American Spirits cigarette as evidenced by the trademark eagle on the white paper portion. Amercian Spirits were not available until 1982.
Orlando's Army uniform has brass insignia on the right lapel, but it is missing from the left. The name tag above the right breast pocket is missing. As a private first class, he would have been in the Army long enough to have at least one or two ribbons, which should be above the left breast pocket. He should have a rifle qualification badge above the left breast pocket. He wears the unit insignia of the 25th Infantry Division on his left shoulder, which means that he was in the division at that time. The division, however, was in Viet Nam, making it highly unlikely that he would be at home in the U.S., wearing the winter uniform of a division in the tropics during the summer.
