I am currently reading Disney War by James B. Stewart, and came across this TRON reference: "One reason the Disney live action studio hadn't had a hit since The Love Bug was that (E. Cardon) Walker (Disney chairman in 1982) did not believe in marketing and advertising. TRON, an expensive, and computer generated science fiction picture, opened a few weeks after E.T.:The extraterrestrial and Annie. The competing studios were spending a then astronomical 10 million each on advertising and marketing campaigns. Walker refused to raise the minuscule marketing budget, citing Walt's adage that the only publicity worth the money was free. When TROn finished it's opening weekend in a dismal 6th place, Wlker still refused ti increase advertising, insisting that word of mouth would come to the rescue. Much of the 17 million cost had to be written off"

And a second reference in Tim Burton's bio book: Burton on Burton refering back to when he was working at Disney:" I remeber they were doing that movie TRON. I was just a lowly in-betweener at the time,and there were all these computer guys pitching stuff that only now are they able to do, and not even all of it."
Obviously Tim doesn't get it!
