Sarah Palin wrapped up her new memoir "Going Rogue" in just four months after the book deal was announced _ you betcha she did! _ but did she write it alone, or did she have help?

Curiosity about the making of Palin's best-seller inspired one of the questions in this edition of "Ask AP," a weekly Q&A column where AP journalists respond to readers' questions about the news.

In a recent AP story, Sony Chief Executive Howard Stringer said a 3-D version of "Men in Black" is being considered, and he said it isn't clear what other Sony movies might be reissued in 3-D.

It's my understanding that a 3-D movie is photographed using two different images, one for each eye.

So has Sony been shooting its films in 3-D for years but just releasing them in 2-D? Or is the company planning to re-shoot those old 2-D titles from their film library in 3-D? Or is it planning to use some sort of fake 3-D simulation process on the original films?

According to the people at Sony Corp., CEO Howard Stringer was referring to an upcoming "Men in Black" movie, which would be the third in the series.

It's still in development, and the company's movie studio is considering shooting and releasing it in 3-D, but it hasn't made a decision yet.

Indeed, 3-D movies require two images. For live-action sequences, that generally requires a special camera set-up that captures left-eye and right-eye images. For animated movies, that can be done on a computer.

Sony has developed its own single-lens 3-D camera, which it showcased in Japan in October.

But the studio says it hasn't been shooting its 2-D films with 3-D cameras and squirreling away the footage.

It has developed some 3-D titles, including the recent "Cloudy with a Chance of Meatballs," "Open Season" (2006) and "Monster House" (2006). It's possible those films may be rereleased in 3-D on home video as televisions catch up with the technology in theaters.

There are also ways of converting old 2-D movies into 3-D artificially. Sony says it is monitoring such developments but has not yet announced any plans to remaster 2-D hits from its library into 3-D.
