It is not going to be easy to contact a non-gaming IP holder to try and talk to them about it.
I would recommend you work on your game first and get it really polished. Do a lot of playtesting with a variety of people and get the game to a good point. Then you can contact one of the game publishers that work with IP licenses and see if they have the contacts and would be interested. Likely you would have to set up a meeting with the game pub first to let them see the worth of the game.
Most TV and movie companies are at least somewhat interested in pursuing outside licenses, but you need to have a good game and a proven publisher behind it to impress them enough to move forward.
At least, that is what I get from listening to publishers talk about what it takes to get a game published. YMMV.
