The Walt Disney Co. announced today that they've finalized an exclusive deal to construct attractions based on James Cameron's blockbuster hit movie "Avatar" at its theme parks, beginning with its Animal Kingdom park in Orlando, Fla. Construction on the Avitar attractions is set to begin in 2013 and is expected to be completed about 3 years after that. The Avatar attraction is to be an immersive land traversing over several acres and will cost around $400 million. Chief executive officer Bob Iger made the announcement at a news conference on this morning. Cameron, who's working on the 2nd and 3rd installments of the top-grossing motion picture of all time, said the attractions would be a way to bring the lush world of Pandora to life, and would include animatronics and possibly multimedia shows that use 3-D and holographic technology. "This is a pretty darned exciting project," Cameron told reporters. Walt Disney shares rose 30 cents to $32.81 in afternoon trading Tuesday.
