This turns out to be a film promotion, but it’s still worth watching.
First the clip, then the question.
Question: how many people were not actors? It tells you they recruited actors, but there’s no specification of who were not. I doubt they would take the risk in the USA of pulling a stunt like that in case the unsuspecting victim suffered a heart attack with the shock. (It would be cruel to give someone a fright like that.)
Like the last Bond promo, I admire the idea and the execution, even if what I am watching is as fake as a four pound coin.
