Husband-and-wife team Win Butler and Regine Chassagne lead the band Arcade Fire, an art-rock outfit that hails from Montreal.

The seven-member band, which deploys everything from piano, sax and violin to dobro, harpsichord and hurdy-gurdy, has two albums to its credit: Neon Bible and 2004's Funeral.

Steven Bach's biography Leni: The Life and Work of Leni Riefenstahl examines the filmmaker who celebrated the Nazi ideal and created the Third Reich's iconic images in Triumph of the Will and Olympiad. Bach details Riefenstahl's ruthless, opportunistic ambition, analyzes her "self-righteous entitlement," and explores her relationships with Hitler, Goebbels and Albert Speer. What emerges is a compulsively readable and scrupulously crafted work.

Judd Apatow has been a writer for Larry Sanders and Ben Stiller, and he worked on the cult-favorite TV comedy Freaks and Geeks. But you'll know him as the writer-director of the hit film The 40-Year-Old Virgin.

Now he's back with Knocked Up; guest host David Bianculli talks to Apatow and to Knocked Up star Seth Rogen, who plays an oafish slacker confronted with the prospect of fatherhood after a one-night stand.

Yanar Mohammed, an internationally renowned Iraqi activist, founded the Organization of Women's Freedom in Iraq to advocate for women's rights. It's an uphill fight: From the 1950s to the 1970s, Iraqi women could legally work, study, marry and divorce, and wear what they wanted, but the new constitution in Iraq, based on the Islamic Sharia law system, denies women the civil and social rights guaranteed to men.

Writer and editor David Talbot founded the online journal Salon.com; he was editor-in-chief from 1995 to 2005, and still serves as board chairman of Salon Media Group. He's written a book about Robert and John F. Kennedy called Brothers: The Hidden History of the Kennedy Years.

Actor-director Kevin Costner won the Oscar for Dances With Wolves, but he made his first movie splash as a corpse in The Big Chill: He played the friend whose suicide brings a group of old friends together, but all of his speaking scenes were cut from the film, so all we see of Costner is a shot of his hand peeking out from beneath a sheet.

Costner went on to star in Field of Dreams, Tin Cup, Waterworld, Bull Durham and The Upside of Anger; in his latest film, Mr. Brooks, he plays a loving family man who's also a serial killer.

Journalist Marcus Stern and his colleagues at the San Diego Union-Tribune won a Pulitzer Prize in 2006 for uncovering the bribery scandal involving former U.S. Congressman Duke Cunningham. Cunningham funneled tens of millions of dollars in post-9/11 contracts in exchange for millions in bribes.

Now Stern and his team have written a book about the scandal: It's called The Wrong Stuff: The Extraordinary Saga of Randy "Duke" Cunningham, The Most Corrupt Congressman.

Documentary producer Huw Cordey helped create the staggeringly ambitious BBC series Planet Earth. The series was five years in the making and was shot in 62 countries on every continent. It was broadcast in the United States on The Discovery Channel, and is now available on DVD.

Comic Don Rickles is known for insulting his audiences on stage, but he doesn't consider himself an insult comic. His heyday was in the '50s and '60s, on TV and in Vegas. Frank Sinatra, an early fan, helped get him noticed. Now Rickles has written a memoir, Rickles' Book.

During his early-'70s heyday, shock-rock icon Alice Cooper dressed like a ghoul, with a gaunt face and mascara-streaked eyes, performing cartoonishly violent onstage stunts.

His hits included "I'm Eighteen," "School's Out," and "Welcome to My Nightmare."
