As a touch of Hollywood inside humor, Jimmy was given one line in
Invaders from Mars (1986), the remake of the 1953 sci-fi classic--
Invaders from Mars (1953)--in which he starred. As he approaches the hill where the flying saucer has
allegedly landed, he says, "I haven't been here in 40 years". As the cable
channel American Movie Classics noted, that was fairly close. It had
actually been 33 years.
