When you watch a movie chances are you notice popular products or brand names being mentioned and shown on screen. This is called product placement and companies pay a lot of money to have their products featured on screen.

How a certain product is used can frame how the audience perceives it. Apple apparently has put a lot of thought in to how they want people to view and feel about their products.

In a recent interview with Vanity Fair, director Rian Johnson was talking about his newest film Knives Out and discussing how he sets up a scene. During the discussion Johnson talked about using the iPhone in the scene and how Apple does not want bad guys to use iPhones while on screen.

This is a huge spoiler alert for anyone watching mystery movies going forward because now all you have to do is pay attention to what kind of phone each character is using. Unless of course all the phones used in the film are not iPhones, or the film is set in a time before iPhones were invented.

I think this is extremely fascinating because I would never have put a second thought into what kind of phone the character is using. I guess it’s a good thing I am not in the marketing department for Apple.
