Kovacs helped develop camera tricks still common decades after his death. His character Eugene sat at a table to eat his lunch, but as he removed items one at a time from a lunch box, he watched them inexplicably roll down the table into the lap of a man reading a newspaper at the other end. When Kovacs poured milk from a thermos bottle, the stream flowed in a seemingly unusual direction. Never seen on television before, the secret was using a tilted set in front of a camera tilted at the same angle.
