When he agreed to direct a sequel to his megahit Men In Black, Barry Sonnenfeld was determined not to repeat himself. "We had to bring back Will Smith and Tommy Lee Jones, because so much of what made that first movie work was the relationship between them," he explains. "They're like Abbott and Costello. You can't have one without the other . . . there's a karmic thing between these two. The audience likes to see them bicker. The first movie takes place over three days and MIIB over two, so they only know each other for five days—but it looks like they've been together for 30 years!"
