Character mistake: When Brenda first witnesses Connor and the Kurgan fight, Kurgan says "I am the only one." Afterwards, Brenda asks "What does he mean by there can be only one?" She somehow misheard Kurgan and thought he said the movie's iconic catch phrase.

Character mistake: There are signs out front as the Spenglers arrive at the dirt farm. One of the signs is a call back to a scene in Ghostbusters 1984.

When Finn Wolfhard reads it he misquotes the line saying "The sun became as black as cloth."
