I saw a 1970’s thriller movie about a man who appears in the mirror and grabs a boy to bring him into a place where boys are forced intto labor. The boy tries to escape the man and then once seen as he’s holding onto something, the man throws an ax at the boys hand and chops it off. The boy escapes but the man takes the hand, the movie ended where the boy escaped and he was with his brother and his brothers wife. Now the boys in his room and as he looks in the mirror, he sees the man hanging on the wall as if it were a cool jacket on a hook. The man called out to him and said, “Boy!” And then the man just grabbed the boy took them in the mirror, and now you see the boy walking in single file with other boys and it look like they were caring backpacks. The movie was really scary I just don’t remember the title.
