Pic kicks off World Animation Celebration

It was, well, an animated crowd that turned up the premiere of Warner Bros.’ “Osmosis Jones” at Hollywood’s Egyptian Theater Tuesday night. Pic kicked off the World Animation Celebration, which runs through Sunday.

Try getting Chris Rock — the voice of the cartoon white-blood cell Osmosis Jones — to say “endoplasmic reticulum,” and you understand the challenges faced by pic’s animation directors Tom Sito and Piet Kroon, who agreed that in the end, they created, along with producer and “Jones’ ” live-action director Bobby Farrelly, an entertaining hybrid of sensibilities.

“There was a lot of back and forth between us,” Sito said. “We would make sure that the transitions worked as smoothly as possible. We explained the animation process to them, and they explained comic timing to us.”

Both Sito and Kroon said that their proudest moment came when the animation team was able to out-gross the men responsible for “There’s Something About Mary” and “Kingpin.” “I mean, they were the guys who put sperm in (Cameron Diaz’s) hair!” laughed Kroon.

“Sometimes, when we came up with stuff, they had to rein us in!” Sito added.

Among the 3-D crowd enjoying the 2-D pic’s after-party in the theater’s courtyard were Warner Bros. honchos Lorenzo di Bonaventura, Alan Horn and Dan Fellman; stars Bill Murray, Elena Franklin, Laurence Fishburne, William Shatner and Molly Shannon, plus Farrelly; and guests Jeffrey Katzenberg, Kari Wuhrer and Bud Cort.
