Disney is running a promotion with their new 'Disney Movies Anywhere' service that allows you to get a free iTunes copy of The Incredibles when you link your US iTunes account to a new Disney Movies Anywhere account. This one takes a bit of fiddling around, so perhaps not for everyone, but those who already have a US iTunes account should find it simple enough.
1. First of all, if you're in Australia you will need to use a geo-blocking plugin like 'Hola' for Chrome to make your browser think you're in the US.
2. Go to http://www.disneymoviesanywhere.com and register for a new account.
3. Once logged in you should see a link to the promotion offering a free copy of The Incredibles for linking to your US iTunes account. Click on it and follow the steps to do so.
4. Voila. You should now have a copy of The Incredibles both attached to your US iTunes account and to your Disney Movies Anywhere account.
An added bonus is that any Disney films you have purchased or redeemed on iTunes in the past will now also be part of your Movies Anywhere account. The same is true for future purchases or redemptions on either service; you will always get both copies.
Personally, I have had trouble playing back movies from Disney Movies Anywhere in browser, even with 'Hola' enabled, but the iTunes copy of The Incredibles plays just fine on my Apple TV, iPad, PC, etc.
Granted this service will probably come to Australia in the future and work with AU iTunes accounts, but for now it's a nice freebee if you already have a US account up and running, or are just super keen for a digital copy of the The Incredibles. :)
