After you enter that code, you're taken to a page where you can redeem an UltraViolet copy. We chose Flixster as it's a service we've used before — it's owned by Warner Bros (rather than Universal, who distributes The Bourne Legacy) and is integrated with the Rotten Tomatoes movie critic network.
It's important to realise that what service you choose here doesn't really matter. You can access your entire UltraViolet collection through any of the services available. We know that Flixster will be available in Australia when UltraViolet launches here, but more will pop up soon. It doesn't matter which you choose, so go with whichever one you like.
