Pixar's Inside Out opens today in 3,946 theatres according to Box Office Mojo. The film is getting universal praise from the critics with a stellar 99% at Rotten Tomatoes. Their consensus: "Inventive, gorgeously animated, and powerfully moving, Inside Out is another outstanding addition to the Pixar library of modern animated classics". However, with dinosaurs still ruling the World, analyst expect this to be the first Pixar film not to open on top. BOM projects an outstanding, but second place, weekend with $71 million, while Box Office Prophets is in agreement with a $72 million prediction.
