Wyrsch will be on hand at a special Back to Space-Con premiere event at the Balboa Theater, along with former Chronicle writer and Creature Features host John Stanley, and Ernie Fosselius, the man behind the Star Wars spoof Hardware Wars (1978).
"I think people get to see the simplicity that was there in the seventies, it wasn't so regimented like they are nowadays," says Wyrsch. "And people love that."
