As movie magic technology has become more advanced, the border between live action with special effects and full animation has been blurred. Peter Debruge of Variety wondered when the Academy would change their rigid constraints on what qualifies for an animated film in his editorial, “Oscars: With Films Like Gravity, Where Does Animation Branch Draw the Line?” Debruge points out that Gravity director Alfonso Cuaron likened his movie’s special effects to the animation process, but it is notable that his movie also featured Sandra Bullock and George Clooney in non-animated form, so for the time being it seems unlikely that studios would even want for movies like that to count as “cartoons” in Oscar’s eyes.
