For true movie buffs nothing is less trivial than classic movie trivia. It is a badge of honor to be able to recite the names of not only the starring actors of a boatload of past films, but most of the supporting cast as well. Some little gem like knowing that then unknown Kevin Costner played the corpse of Alex, the deceased friend in “The Big Chill” is merely Trivia 101 for the genuine wiz.
Movie mavens like nothing better than to get together and discuss all aspects cinema, not the least of which is a solid knowledge of who played who in what, and why that performance is significant. Classic film actors tend to have at least a few obscure roles on their resume, and being able to name these is where the real prestige lies.
An instance where a major movie star stepped out of his or her comfort zone to attempt a surprising role (think Clint Eastwood in “Paint Your Wagon,” or “Marlon Brando in “Guys and Dolls”) is another possible category of “Who was that actor” trivia.
With the advent of the Internet and Google, hopefully having a vast knowledge of movie trivia hasn’t been devalued.
