I was doing research on the web last night to find out what breed of cat is used in the movie. Could not find that information about this movie. To me, it really looks like a Maine Coon. FReepers know I am a Maine Coon aficionado (mine is watching me type this at very close range...), so I know what a Coon looks like. Is this a Coon, a Coon mix, or a Norwegian Forest Cat (very closely related species which looks a lot like a Coon)? In any case, the cat is really a beauty!
The cat breed in the newest Christopher Walken film looks to be a Ragdoll. He (or she) appears to be a lynx point mitted bi color.
