Is David Letterman obsessed with Tracy Morgan? Last week, he grilled Tina Fey on her '30 Rock' costar, the result was this gem of a clip. Last night he turned his questions on Luke Wilson on 'Late Show With David Letterman' (11:35PM ET on CBS).

"He's a real force of nature," Wilson said. The duo were riding around in a picture car, waiting to shoot a scene and Morgan was getting numbers from girls on the street.

"At one point I said, 'Tracy, I think they're ready to shoot this' ... and he said, 'Lou,' and I said, 'It's Luke.' He said 'Lou ... I'm a pervert,'" Wilson said.

Tracy Morgan stories make for good TV.

Luke Wilson and Diane Ladd are turning to an unusual source to find enlightenment: HBO.

According to the Hollywood Reporter, Wilson and Ladd are the latest big names to sign on for HBO's new comedy pilot 'Enlightened.' Starring Laura Dern as Amy, the series tells the story of " a self-destructive woman who after a meltdown has a spiritual awakening and becomes determined to live an enlightened life, creating havoc at home and work."

Have you heard that Laura Dern is starring in a new HBO comedy called Enlightened? Of course you have. What might be news is that both Luke Wilson and Diane Ladd are joining the cast of the same show.

Dern plays a self-destructive character named Amy who tries to clean up her own life. Ladd is Laura Dern's real-life mother and she's best cast as, a drum roll please, Amy's mother. This is an example of art imitating life. Of course, since the pair have already done movies and television together (including a dual Academy Award nomination for Rambling Rose, they're probably used to each other by now.

Wilson plays Amy's drug-abusing ex-husband. His last television appearance was a recurring role on That 70's Show. This is a step down from his usual movie roles (such as the under-appreciated Idiocracy). However, this is definitely a step up from his recent AT&T commercials.
