The "Disneyland-style" park, as Moscow city hall calls it, will be Europe's largest indoor theme park. It has been a long time in the making. DreamWorks Animation (DWA) signed a licensing agreement with a local developer in 2013, aiming to build three parks across Russia. At that time, the animation company called Russia "one of the most important markets in the world."Source:DreamWorks is not looking to back out. The animation company confirmed the agreement stands, but refused to comment further. Its theme parks business is based on licensing -- meaning the company sells its right to local developers, rather than building the park itself.
