Basically, yes. It's an extended trailer, usually 15 -20 minutes. But because they use venues like the Magic Eye Theater, Muppet's 3D, and It's Tough To be A Bug, they are usually 3D and utilize the special effects in the theater like lighting, smoke, loud base, or movement. It can result in a better experience than the full movie in the regular theaters. I think movie chains should pay attention! Perhaps DBox (the chairs that moves) is what the start of that.
