Lasseter began to get worried when, in early 1996,
he heard rumors that DreamWorks might be making its own computer-animated movie about ants.
He called Katzenberg and asked him point-blank.
Katzenberg hemmed, hawed, and asked where Lasseter had heard that.
Lasseter asked again, and Katzenberg admitted it was true.
"How could you?" yelled Lasseter, who very rarely raised his voice.
"We had the idea long ago," said Katzenberg, who explained that it had been pitched to him by a development director at DreamWorks.
"I don't believe you," Lasseter replied.
Katzenberg conceded that he had sped up Antz as a way to counter his former colleagues at Disney.
DreamWorks' first major picture was to be Prince of Egypt, which was scheduled to be released for Thanksgiving 1998,
and he was appalled when he heard that Disney was planning to release Pixar's A Bug's Life that same weekend.
So he had rushed Antz into production to force Disney to change the release date of A Bug's Life.
"Fuck you," replied Lasseter, who did not normally use such language.
He didn't speak to Katzenberg for another thirteen years.
