Avatar version 2.0 with extra footage

James Cameron's sci-fi epic "Avatar" revisits global multiplexes this weekend in a quest to pad its record $2.74 billion worldwide box office and hype DVD and Blu-ray Disc special editions.

"Avatar" originally bowed in 2D and 3D on December 18, but the theatrical special edition will be shown only in 3D venues.

To date, "Avatar" has rung up $749.8 million domestically and $1.99 billion in foreign coin. Prerelease projections have "Avatar" fetching somewhere in the mid- to high-single-digit millions this weekend, but execs are more uncertain about what to expect from the rerelease in total.

The version 2.0 "Avatar" also is being released on more than 1,000 locations in 14 foreign territories including the U.K., Russia and Taiwan this week, including 50 overseas Imax sites. The pic's theatrical special edition will bow later in some other countries, with Japan set to get the super-sized "Avatar" in October.
