BURBANK, Calif., May 26, 2011 /PRNewswire/ -- Simba, Mufasa, Nala, Timon and Pumbaa are back and better than ever this fall when Disney's "The Lion King" roars into theaters and homes in breathtaking 3D. A special two-week theatrical extravaganza kicks off Sept. 16, 2011, showcasing the Oscar®- and Golden Globe®-winning film on the big screen in Disney Digital 3D™ for the first time ever, and its highly anticipated home entertainment debut kicks off October 4, celebrating the Diamond Edition release of the epic movie "The Lion King" in high-definition Blu-ray™ and Blu-ray 3D™.
"'The Lion King' is the best-selling home entertainment release of all time—and this is 'The Lion King' like never before," said Bob Chapek, president of distribution, The Walt Disney Studios. "The all-new 3D format immerses viewers in the epic settings and puts them face-to-face with these beloved characters. We're showcasing one of the all-time favorite Disney movies in theaters and making it available in Blu-ray hi-def and in Blu-ray 3D—it's the must-see, must-own title for everyone."
Nearly a decade since "The Lion King" last appeared on the big screen, the upcoming theatrical release invites new generations into the "Circle of Life."  The two-week, 3D-only presentation is a planned wide domestic release—the biggest since the film's 1994 debut—and the film's first-ever 3D release.
The Blu-ray debut marks the first time "The Lion King" has been available in any form since 2004.  Featuring pristine high definition picture and sound, the Blu-ray creates an incredible at-home experience with a host of picture and sound enhancements, interactive features and bonus content, including a new set of hilarious animated bloopers.
"The Lion King": Diamond Edition home entertainment release will be available from the Disney Vault for a limited time only beginning October 4 as follows:
4-Disc Blu-ray Combo Pack (for the suggested retail price of $49.99 U.S./ $56.99 Canada)
"The Lion King" = Blu-ray 3D + Blu-ray 2D + DVD + Digital Copy™
2-Disc Blu-ray Combo Pack (for the suggested retail price of $39.99 U.S./$46.99 Canada)
"The Lion King" = Blu-ray 2D + DVD
8-Disc Trilogy (for the suggested retail price of $100.00 U.S./ $115.00 Canada)

And the one-disc DVD Edition will be available on November 15.
"The Lion King," first released in 1994, won the Oscar® for Best Original Score (Hans Zimmer) and Best Original Song (Elton John/Tim Rice "Can You Feel the Love Tonight"), earning Golden Globes® in both categories, as well as for Best Motion Picture—Comedy or Musical.
The film inspired an immensely popular, Tony Award®-winning Broadway musical, which is currently featured on stages worldwide. It became the seventh longest-running musical in Broadway history in January 2011. 

I guess re-releasing movies in 3D will be Disney's latest cash-in since they've stopped making sequels.  :)
