Yes it's out on iTunes for USD 19.99. But sadly the movie never made it to Malaysian cinemas. Sure you can buy and watch it on your computer but you can never get the "movie experience" which I think is what this show deserves.
However, it seems the show has made it to Pirate Bay (and a clear DVD version too). I certainly don't advocate pirating and downloading it there as that's is like stealing from the efforts of the producers.
So how? Have you watched this chess movie yet? I certainly recommend it especially to young students of chess looking for inspiration. Sure it has been made into Disney's flavour of fairy tale endings but still most of it is based on real life.
