Robert Patrick was known for portraying the T-1000 in Terminator 2: Judgment Day (1991), James Cameron’s masterpiece. In the film, his human form is a police officer looking for John Connor (Edward Furlong), who was protected by the T-800 (Arnold Schwarzenegger) and his mother (Linda Hamilton).
In Wayne’s World (1992), Robert Patrick just played a normal police officer and saw Wayne Campbell (Mike Myers) in his car. The officer asked Wayne, “have you seen this boy?” as he held a picture of a young boy. Since Wayne is a fan of the Terminator films, he screamed loudly as he sped up his car away from the officer. Wayne thought that the T-1000 was real after all. However, it is just an officer who wanted help into finding a missing boy. Thus, Wayne was scared for no legitimate reason. Wayne should have known that art imitates life and life does not imitate art.
