Watch tv with him and slowly try to talk to him about the tv show he's watching and then try to get him on your side, and once he acknowledges you, you can go ahead and talk to him about what would happen to him if he does that thing and what will happen to him in the future and then invite him to play games outside or to stay at your house and hangout and play lots of games good for him and pick the channels to watch on the tv that are suitable for him, he might just develop an interest in both you and what he does which is foreign to him.

Note: This is based on experience.
