Apple has announced that iTunes customers in the States can now purchase and rent films in "stunning" HD through the iTunes Store.

The company is offering "box office favourites" such as new Bond outing "Quantum of Solace" and teen vamp flick "Twilight" for $19.99 to own and $4.99 to rent.

Apple says that the HD versions will be available around 30 days after release and a non-HD smaller file will be bundled for playback on portable devices.

"Movie fans are going to love being able to buy and rent films including 'Quantum of Solace' and 'Twilight' in stunning HD from the iTunes Store", said Eddy Cue, Apple's vice president of internet services.

"Customers have made HD content on iTunes a hit, with over 50 percent of TV programming being purchased in HD when available".

In the UK customers can purchase high def TV content, with some HD movies available through Apple TV.
