Invaders From Mars (1953)

Young boy cries martian in this sci-fi cheapy classic. He can't convince the townspeople of this invasion because they've already been possessed by the alien beings. His parents are zapped by the little green things first, making this perhaps an allegory for the missing Eisenhower/Stepford years. Includes previews of coming attractions from classic science-fiction films. Remade in 1986 by Tobe Hooper.
