A few years ago I watched a movie trailer, but now I can’t remember the name.
It was about someone whose shadow didn't follow him. It was like a regular shadow, but it wasn't doing the exact things that the man was doing.
For example, the man opened the refrigerator while holding a bottle of milk, but the shadow stood behind him without doing anything. There was also another scene; the shadow's hand came out of the wall. The movie was not animated and the language was English.
