Character designer Peter de Sève welcomed the new plot addition, since he could not think of any other giant mammal to put into the story. The "lost world" approach led to colorful dinosaurs, because "the dinosaurs didn't have to be just brown, and you can take liberties because no one knows what color they were", according to de Sève. Rudy's design was inspired by the Baryonyx because of his crocodile-like look, which de Sève considered even more menacing than the T. rex. Release Ice Age: Dawn of the Dinosaurs held special screenings on Father's Day, June 21, 2009, in 330 theaters across the United States, exclusively in 3-D. That day was chosen due to the film featuring a theme of fatherhood. Widely, it was released on July 1, 2009. The film was released in RealD 3D where available. This sparked some controversy when Fox announced that it would no longer pay to supply 3-D glasses to theaters, leading to a number of exhibitors threatening to show the film in only standard 2-D projection. Home media Ice Age: Dawn of the Dinosaurs was released on standard DVD and high-definition Blu-ray Disc in North America on October 27, 2009. Two versions of the DVD were released: a single-disc DVD, and a "Scrat Pack" double DVD pack with three Scrat games. The 3-disc Blu-ray combo pack included a Blu-ray, the single-disc DVD, and a Digital Copy, as well as an Ice Age digital story-book maker, commentary by director Carlos Saldanha, deleted scenes, making-of featurettes, the two Scrat shorts: Gone Nutty and No Time for Nuts (that each originally came on home video for both the first and second films), and a how-to-draw Scrat tutorial with the filmmakers.
