I came across a newspaper article containing the following text:
Walt Disney studios will have invested more than four years and an estimated $4 million by the time their feature length "The Rescuers" is released late next year.
That dedication to the art of animation is why the Disney people never have entered the television field.
"We can't do our kind of stuff in that medium," explains Don Duckwell, head of animation at Disney. "Sure, we like to get our work in front of people any way we can, but economics prevents it. Actually, Walt decided many years ago that we would not take shortcuts in our animation, and we feel that's still the best way to operate."
I commend Disney's decision, though it's a shame to find out that I must have hallucinated DuckTales.
