Filmmaker Morgan Spurlock did all those things, but he decided to do something else: Hunt down the world's most-wanted terrorist.

Spurlock, famous for the 30-day, all-McDonald's diet he ate for his 2004 documentary, "Super Size Me," had already started work on a movie about the war on terror. But with the news that his then-girlfriend (now his wife), Alex Jamieson, was pregnant, Spurlock said, "that really shifted the focus for me, mentally."

"While I was going out to find this guy, . . . it really also became, 'What kind of world am I bringing my child into?' '' Spurlock said Tuesday in an interview in Park City, a day after his film, "Where in the World Is Osama bin Laden?" premiered to an enthusiastic crowd at the 2008 Sundance Film Festival.

In his humorous and thoughtful movie, Spurlock travels the Middle East following Osama's trail. He is embedded with a U.S. military unit in Afghanistan and rides along with the Tel Aviv bomb squad. All of this happens while Jamieson counts down to her due date. (It isn't spoiling the movie's ending to say that their son, Laken, was born in December 2006.)

Jamieson, during the Q-and-A session after Monday's screening, said she was apprehensive about her partner leaving for dangerous lands. "The one thing I won was 'no Iraq,' " she said. "I said I'd leave if he did that."

Much of the movie shows Spurlock talking to ordinary people all around the Middle East. Most of them don't like bin Laden - but they're not crazy about President Bush, either.

"It was hard for me to hear people telling me their opinions [about America], . . . and I think it's going to be hard for other people to listen to," Spurlock said. "But we have to start listening. . . . We have to really start thinking beyond our borders."

And, Spurlock said, Americans must look beyond Osama to what he has inspired. "Osama bin Laden is the figurehead of the whole thing," he said. "He is a global franchise. . . . The web that has been put out by al-Qaida is now worldwide."

Monday night's screening is a homecoming of sorts for Spurlock, who went from being an unknown filmmaker to a maverick consumer crusader when "Super Size Me" debuted in Park City four years ago.

Spurlock received a directing award at Sundance '04, and later an Oscar nomination. He wrote a companion book. Jamieson, a vegan chef, published a diet book. And Spurlock took the "Super Size Me" formula to TV with the FX series "30 Days." (For the third season, out later this year, Spurlock worked 30 days in a West Virginia coal mine, during the Crandall Canyon mine disaster in Utah.)

Now Spurlock is looking forward to another harrowing adventure: Fatherhood.

"Getting married and having a child with Alex, it changes your whole value system, of what you find important," he said. "For me, that [baby] and that woman are the two most important thing in my life. Nothing else really matters."

* "Where in the World Is Osama bin Laden?" will play at one or two more festivals, and then hit theaters nationwide in April. The Weinstein Company bought distribution rights last February at the Berlin Film Festival, on the basis of a few minutes' of Spurlock's footage.
