If you have any movie buff friends, you know that they’re always offering up never-before-heard pieces of trivia about films from the past and present. These tidbits are not only cool to know, but they come in handy at trivia nights or when you’re playing HQ.
Picking up this kind of information is actually useful beyond just impressing your friends or winning a free beer at trivia night.
