Some of Sony Corp.'s movies sold through Apple Inc.'s iTunes store are now available with extra features that enable people to search scenes for actors and bits of dialogue by typing terms into a computer.
Other features allow viewers to choose clips to share on Facebook and Twitter and check where songs from a soundtrack appear. A link to the iTunes store makes music purchases easy.
All three features are available now on "Burlesque" and "The Others Guys." The non-music features are available on "Salt" and "Resident Evil: Afterlife" and will be available on "The Tourist," when it is released March 22.
Studio Senior Vice President Rich Berger said in a statement that adding the features boosts the value of Sony's digital movies and makes them more collectable.
