Weird Science (TV Series) - Cast

Cast

• John Mallory Asher takes over the role of Gary Wallace. Unlike his counterpart in the film, Gary is a poor student and a slacker, always looking for shortcuts to get what he wants (usually to impress girls). His father, Al (Jeff Doucette) is a plumber. His mother Emily is played Joyce Bulifant, Asher's real life mother.
• Michael Manasseri takes over the role of Wyatt Donnelly. Wyatt's wealthy parents are usually out of town, leaving him and his older brother Chett alone in the house. Most stories have him as the more cautious member of the group, more reluctant than Gary to use Lisa's magic. He is more popular with girls than Gary, and several episodes feature Gary being interested in a girl who likes Wyatt instead.
• Vanessa Angel takes over the role of Lisa. Lisa describes herself as a "magic genie," able to grant the boys' wishes, though she does this out of choice rather than duty and is free to deny them any wish she does not want to grant. Once she grants a wish, Lisa is unable to reverse it, no matter how badly it turns out; however, most of her spells wear off after an indeterminate amount of time. Other than those basic rules, the limits of her powers are never clearly defined, and she seems to get more or less powerful depending on what a particular episode's plot requires. Although she is physically manifested, she is apparently still a program running on Wyatt's computer, and she ceases to appear if the computer is switched off. She is addicted to Chunky Monkey ice cream.
• Lee Tergesen takes over the role of Chett Donnelly. Chett is a military school graduate who turned down his commission, claiming that he did not want to be sent overseas to work for "Third-World slackers"; he lives with his parents and shows no interest in getting a job. Paranoid and angry, he takes out his frustrations on Wyatt, though less sadistically than in the movie; mostly he takes Wyatt's things without asking and calls him names like "wuss-boy" and "pit-lick." He also has a vendetta against Scampi (Bruce Jarchow), principal of the boys' high school, whom he remembers as "Ass-istant Principal Scampi." Most episodes have Chett getting caught up unwittingly in the magical shenanigans, often getting hurt or transformed without knowing what is going on. At the end of the third season, to expand Lee Tergesen's role, Chett was let in on the secret of Lisa's existence; it was explained that Lisa had so often erased parts of his memory that he had developed a mental callus making him immune to erasure. He occasionally had hints of sexual tension with Lisa.
