Antimatter Man
When an experiment in atomization goes awry, John (Guy Williams) is thrust into a bizarre antimatter world, festooned with orange grass and polka dot leaves–and the home of John’s own evil lookalike. While his villainous doppelganger takes his place at the Robinson camp, the “real” John is closely guarded by “Drun”, the nasty antimatter twin of Don West (Mark Goddard), and by an evil clone of the Robot. It is up to the genuine Robot, with the help of Will (Billy Mumy) and the hindrance of Dr. Smith (Jonathan Harris), to set things right., During an experiment, Professor Robinson finds a parallel universe, home to evil clones of himself and Major West., Will and the robot try to rescue the kidnapped Prof. Robinson—in a macabre world of orange grass, polka-dotted leaves and animated rocks. John/Antimatter: Guy Williams. Smith: Jonathan Harris. Don/Drun: Mark Goddard. Robot: Bob May. Maureen: June Lockhart.
