Hoping to drive digital sales, 20th Century Fox is selling its sci-fi thriller "Prometheus" through several major online retailers three weeks ahead of the movie’s release on DVD and Blu-ray
disc. “The Ridley Scott film is one of 600 titles to be sold digitally in high-definition for less than $15 -- a discount from the typical retail price of $20,” The Los Angles Times
reports. The movies are available online through Amazon, Apple's iTunes store, BestBuy's CinemaNow, Google Play, YouTube and Wal-Mart's Vudu, as well as through entertainment stores connected to the
Sony PlayStation and Xbox game consoles.
