The intergalactic Thermians, thinking Allen's Jason Nesmith and Weaver's Gwen DeMarco are truly the characters they play on TV, are relying on these conceited actors to save them from an all-too-real adversary.
One of the first comedies to pay homage to the legion of sci-fi diehards that flooded the early internet, Dean Parisot's hilarious Galaxy Quest stars Tim Allen and Sigourney Weaver as the senescent stars of a bygone Star Trek-like phenomenon who are unwittingly swept up in an honest-to-god sci-fi adventure. The intergalactic Thermians, thinking Allen's Jason Nesmith and Weaver's Gwen DeMarco are truly the characters they play on TV, are relying on these conceited actors to save them from an all-too-real adversary. By positing the aliens as fans and offering these performers a real moment to be heroes, Galaxy Quest both satirizes and celebrates fandom, acknowledging the genuine impact fictional touchstones ultimately have on their most devoted consumers.
