Will 3-D revive the market for full-scale theatrical reissues, basically non-existent since an expanded version of “The Exorcist” came out nearly a decade ago? The Hollywood Reporter says Fox is planning to release a lengthened version of “Avatar” in late summer, which would follow the widely expected release of a bare-bones 2D version on DVD and Blu-ray as soon as Earth Day, April 22 (no official release date has yet been announced). James Cameron has been quoted as saying that the loss of thousands of 3-D screens because of contractual obligations to “Alice in Wonderland” may have forced Fox to leave as much as $200 million in “Avatar” ticket sales on the table. As much as 40 minutes of extra footage is said to exist, though older, non-digital IMAX locations can reportedly only handle a film running 170 minutes — 10 minutes longer than the current “Avatar.” Cameron tells USA Today that a 3-D reissue of “Titanic” is being targeted for March 2012 — the 100th anniversary of the liner’s sinking. As I’ve reported here several times, Warner Bros. has looked at tests from several vendors that convert footage from the 1939 “The Wizard of Oz” into 3-D, but none so far has been deemed acceptable.
