Where The Wild Things Are (1983)
First combination of 3D CGI and standart animation
1) Maurice Sendak's children's book Where the Wild Things Are was the basis for Disney's experimental 35mm test footage, directed by John Lasseter (the future animator at Pixar). This revolutionary animation combined (or digitally composited) both: state-of-the-art, computer-generated 3-D backgrounds with traditional, classic hand-drawn animation (digitally inked and painted) for the 2-D characters.
2) Made by MAGI studio.
