 Barry is shown to be surprised by the extraterrestrials. Director  Steven Spielberg (I) (qv) had two crew members hide in boxes off  camera, one in a clown suit and one in a gorilla suit. One popped  out, then the other as the cameras rolled, catching young  Cary Guffey (qv)s bewildered reaction. Spielberg then whispered  to the gorilla to remove his mask, eliciting a smile from Guffey.
