3-D isn't big draw 2nd time around Hollywood isn't seeing as much green in 3-D re-releases as it had hoped. Considered an easy new revenue source after the 3-D re-release of Walt Disney Studios' "The Lion King" popped out of the screen and grossed nearly $100 million last year, most such follow-ups have landed with a thud in 2012. Disney's "Beauty and the Beast" and "Finding Nemo" were both disappointments, grossing $47.6 million and $40.7 million, respectively, in the U.S. and Canada. Twentieth Century Fox and Lucasfilm's "Star Wars: The Phantom Menace" took in a similarly unimpressive $43.5 million in February. Fox and Paramount Pictures' "Titanic" grossed a slightly better $57.9 million domestically last spring. Audiences, it turns out, are very selective about which movies they'll see again in 3-D. The genre's few hits were ones that moviegoers, or the children they took with them, hadn't seen in a long time - or at all. "Titanic," for instance, grossed almost $150 million in China, where few had seen the original 1997 epic romance. That makes the stakes high for Wednesday's 3-D re-release of "Monsters, Inc." Disney executives were particularly disappointed by the weak 3-D box-office take for "Nemo," one of Pixar Animation Studios' most beloved and successful pictures. A soft performance by Pixar's "Monsters" probably would make Disney - and other Hollywood studios - rethink their strategies. "There's a certain cultural cachet for parents bringing their kids to movies like 'The Lion King' the same way their own parents did for them 20 years ago," said Vincent Bruzzese, motion picture president at research firm Ipsos MediaCT. But many of these movies, people have watched it athomewith their kids, so 3-D may not be something new or extra enough to pay the exorbitant cost of going to a theater. The cost of converting animated movies, particularly those made with 3-D computer technology, is extremely low compared with a new production. Disney spent only about $3 million adding 3-D effects to 2001's "Monsters, Inc." Pixar director of 3-D production Josh Hollander said in a September interview with the website Collider that "Monsters" was "a little easier" to convert than "Nemo" because the movie's visuals are less complex. And Pixar guru John Lasseter, chief creative officer of Disney Animation, said in November that the conversions are a worthwhile effort regardless of their commercial success. "We're going through all of the Pixar titles just so we have them," he explained. I just like it, it's kind of cool. How we use it and how it plays in the marketplace? But for the executives at Disney's movie studio, the marketplace matters very much. Advertising and releasing a family film nationwide costs tens of millions of dollars, and ticket sales have to be split with theater owners. That makes it difficult to turn a profit on a box-office gross of less than $50 million. In addition, 3-D re-releases of films that have already been out on DVD and played on television don't enjoy the substantial post-theatrical revenue that provide the majority of profit for new movies. Nor do they tend to do well overseas - with notable exceptions such as "Titanic." Internationally, the 3-D versions of "Beauty and the Beast" and "Finding Nemo" grossed only $17.3 million and $16.5 million, respectively. Pre-release surveys show "Monsters, Inc." is headed for a modest opening, lower than the $16.7-million start for "Finding Nemo." The best hope for it to perform better than its underwater predecessor is a lack of new releases for families with young children over Christmas. Still, Disney does not appear optimistic about continuing its recent 3-D re-release spate. It has no more planned after next September's "The Little Mermaid." "3-D reissues are a title-by-title consideration for us, and there are several factors we look at," Disney's executive vice president of theatrical distribution, Dave Hollis, said in a statement. The most important drivers are the timelessness of the story and the characters, the appeal across multiple generations, and the opportunity to meet a demand in the family market. We remain very judicious about our choices and continue to refine our offerings as we learn more about what drives consumers to these special engagements.

Outside of more "Star Wars" re-releases and "The Little Mermaid" - the last of four animated films Disney announced in the wake of "Lion King" - only two other pictures have been scheduled for 3-D re-releases next year: Universal Pictures' 19-year-old movie "Jurassic Park" and Paramount's 26-year-old "Top Gun."
