Though we live in the era of the multi-hyphenate and multi-tasker, we still get a boot out of personalities we know for one function, showing up in a totally unexpected context, and in doing so revealing an otherwise hidden side—and hidden talents. 

When a non-actor appears on-screen there is a moment of held breath. Will he or she be…good? After all, acting is hard. Acting takes sweat and years of training, whether in techniques by Stella Adler, Lee Strasberg, or doing improv on weeknights for decades, with no break in sight.

And yet, from out of the blue, a soccer star, jazz musician, or gossip columnist will cruise onto the set and turn in the performance of a seasoned vet.

Call them cross-pollinizers, tourists, wild cards, one-hit wonders, or simply one special persona for a moment in time, but these are the naturals who sidestep apprenticeship and turn in memorable movie moments.

Maybe it’s that fresh, unstudied demeanor that clicks with us. A movie star face (that’s you, George Clooney and Julia Roberts) can carry a movie on sheer charisma. But the left-field choice offers something the box-office tested name no longer can: surprise. Non-actors stand out in a production, which often attracts the notice of the Academy, and the audience roots for the untrained, as if they are one of us.

The best recent example is Somali native and former limo driver Barkhad Abdi, who made the switch from working in a Minneapolis shopping mall to a role opposite Tom Hanks in “Captain Phillips,” and garnered an Oscar nomination as a result.

Non-actors are something like temps. Some of them will be hired full-time, and go on to successful acting careers, and some will go back to touring with their band, or whatever they did before they took a turn under the klieg lights. But while they are on the screen, they are all pros. These movies would not have been the same without them!
