What theory did you develop while watching a movie that turned out to be completely wrong?

I misheard a line in "The Strangers" that IMO made the movie better. (Major spoiler ahead) It was one of the very last lines of the film, when Liv Tyler asks the killers why they've been torturing them. What I thought the character said: "Because you're a home."

I took that to mean that The Strangers had a grievance against typical middle-class American families and selected such families to brutalize out of some twisted sense of vengeance. There was an ironic twist to this because the couple they chose was actually not a close family at all--in fact was in the midst of a major breakup. In other words, The Strangers messed up and chose the wrong targets. I wasn't sure what this meant, but it was interesting and had me wondering if there was some larger message about family life that I wasn't quite getting.

What the character actually said: "Because you were home." When I realized this, it completely changed the dynamic because The Strangers' motivations were a mystery, like the scriptwriter couldn't be bothered to come up with in. I prefer my misheard version.
