I was trying to think of this movie from my childhood (1980's) about a kid who is sitting in his room when a giant present with a big yellow bow flies into his window. It's a tollbooth (or phonebooth) and when he steps in it flies out his window and into an animated world. That's all I can remember and I thought it was called "The Phantom Tollbooth" but when I tried googling it nothing came up. Any takers?
