Disney loves to make movies based on rides at their theme parks like they did with Pirates of the Caribbean. They pulling something similar here where the whole movie is based on one of the many themed lands at Disneyland.
Thankfully they have the talented Brad Bird at the helm along with George Clooney, Hugh Laurie and the relatively unknown Britt Robertson. The trailer thankfully does not give too much away of the plot but shows the grand scale of visuals Bird has created and it looks fabulous.
