traditional film is SHOT at 24 fps but converted to 60 for Blu Ray all the time. 24p is optional but not mandatory in the blu ray spec. Digital film is an entirely different thing, Pixar is no different than Rocky, or any other film its generated on a computer and PRINTED to film and then the digital intermediate is used to make a digital copy for the Blu Ray release. Youtube did not create their 60FPS for video games that is asinine. Television has been shot hit and miss at 60 fps since the late 90's so there is that also.
