Why is Looney Tunes: Back in Action on the list?
Who Framed Roger Rabbit? was nominated for (but didn't win) Best Art Direction-Set Decoration; Best Cinematography; Best Sound.
It was nominated for (and won) Best Effects, Sound Effects Editing; Best Effects, Visual Effects; Best Editing
It also received a Special Achievement Award for animation direction and creation of the cartoon characters.
I realize there was no "Best Animated Feature" Oscar in 1989, but I'd say even though WFRR and LT:BiA contain animation, they are not animated features.
