Marge Simpson's gravity-defying blue beehive is a hybrid creation, Matt Groening has revealed.

Marge, Homer and the rest of the Springfield gang will make the leap from TV to the big screen when "The Simpsons Movie" opens Friday.

In the film, the Oval Office is occupied by President Arnold Schwarzenegger.

"We needed a president that would make people laugh," Groening told the magazine. "And Schwarzenegger was the obvious choice."

In 18 years on Fox, "The Simpsons" has taken several swipes at Rupert Murdoch, the network's owner. Groening said Murdoch has been gracious every time the two men have met.

"He played himself on the show, and we wrote the line, 'I'm Rupert Murdoch, the billionaire tyrant, and this is my skybox,' as his entrance line," Groening said. "He performed it with great zeal."
