Close Encounters of the Fourth Kind: Infestation from Mars is the brainchild of Elliott Haimoff, the film’s executive producer, who is a tropical biologist and maker of science documentaries. Mr. Haimoff credits producer Barbara Sharp, a former area resident, with persuading him to film his latest project in northwest Ohio. Kerstin Khalfani, a bodybuilder and actress, plays Eve II, a Martian who takes over the body of a local housewife and terrorizes the town, sucking the brains from unsuspecting humans.
