We’ve had ninjas all wrong. The real deal is they make themselves invisible in whatever environment they‘re in. For some theater production in the past, the director dressed his sneaky murderer as a sceneshifter, because audiences were used to seeing these figures in black lurking around the set and wouldn’t expect them to interact with the plot, much less kill somebody. So what we think of as a ninja costume is just a Japanese stagehand outfit. To be really ninja-like, you’d want to dress as someone truly invisible. Like a homeless veteran. On a busy corner. With a cardboard sign.
