 Irwin Allen, the creator of the "Lost in Space" television series, selected May to fill the role of the robot, the sidekick of the Robinson family, after May was sent to see him about the part; Allen promised May, "If you can fit in the suit, you've got the job".Bob donned the suit for the first time in front of Allen, and made the suit fit.When he exited the suit (which was made of metal and fiberglass) for the first time, he was cut and bleeding, but very happy that he had got the part.
