4. Brian Smyj - "What, Do You Got Your Period?" Guy In The Departed
The Role: A bar patron who is sitting next to Billy (Leonardo DiCaprio) when he hears him order a cranberry juice and jokes, "It's a natural diuretic. My girlfriend drinks it when she's got her period. What, do you got your period?". Leo responds by smashing a glass over his head.
Why It's Amazing: Extras rarely get roughed up so violently, but Smyj no doubt got the role because of his main profession as a stuntman. The sardonic delivery of the line combined with how well he sells the hit makes it clear why he's worked on so many famous productions; if there's ever an empty spot on set, the guy will often put on his acting cap and fill the gap (he was recently both stunt co-ordinator and actor in The Place Beyond the Pines).
What Happened?: Given how busy he keeps himself - he's working 8 stuntman jobs in 2013 alone - it's no surprise that we don't see him acting too often.
