French Stewart became a father shortly after being told by doctors that he had “the most useless seed the medical community had ever witnessed.” Take that, science! His role on Third Rock from the Sun made him a “national treasure” (his words). Since then he can be seen in Inspector Gadget 2, Home Alone 4, Beverly Hills Chihuahua 2 or any sequel to a children’s movie that none of the original cast members want anything to do with.
