I was talking with a woman at work and I mentioned I’d seen the first Dune in 70mm Imax.
She said, “Isn’t that pretty small?” For a split second, I had no idea what she was talking about. Then I realized she thought “70mm” was the screen size, not the film stock. I couldn’t help laughing. But once I explained she laughed along with me. I still chuckle a little thinking about it.
