Peter Graves (Mission Impossible, Scream of the Wolf) and a young Kathleen Quinlan (Event Horizon) co-star in WHERE HAVE ALL THE PEOPLE GONE? (1974), about a father, son, and daughter who find themselves coping in a post-apocalyptic world. This time, the world-wrecker is a sudden, massive solar flare, poisoning exposed human beings with radiation and reducing them to piles of dust.
