Apple said Thursday that it will begin offering movies for sale and for rent in high definition from its iTunes Store. The HD titles will cost $19.99 to own and $4.99 to rent, about a dollar more than standard-definition fare. While they can be purchased on the same day as their DVD counterparts, they will not be available as rentals until about 30 days after release. Only a handful of titles were mentioned in Apple's news release. Recent blockbusters Twilight and Quantum of Solace can be downloaded on March 21 and 24 respectively, while already released Transporter 3 , Punisher War Zone and "other select titles" are being made available at once.
