Being an actor is a weird job. They”re literally getting paid to play dress-up. Being an actor in a superhero or sci-fi/fantasy job is even weirder as they are professionally cosplaying for our enjoyment. When the cast of Game of Thrones or Arrow are ready for the director to yell ‘Action!” they”re still just regular folks who are wondering when lunch is. Or if they remembered to start the washer before they left the house.
Or, in the case of Stephen Amell, if they could get away with a Starbucks run. You know what? He should totally do this. For posterity. And film it. For posterity.
