'Dancing With the Stars' main man Tom Bergeron is playing Bobby Mann -- a late night talk show host who gets canceled permanently on the April 12 episode of 'Castle,' which airs on ABC immediately after the 'DWTS' two-hour performance show. It's up to series star Nathan Fillion and his TV detective partner, played by Stana Katic, to find out who killed Bobby.

AOL spoke with Bergeron, who weighed in on 'Castle,' the current -- and arguably most-talked about -- cast of 'Dancing With the Stars,' and how he handles those pesky TMZ.com interviews.

News that New York Times reporter Bill Carter is working on a pseudo-sequel to his groundbreaking book The Late Shift' made a smile creep across my face. I haven't yet read the book, but the buzz it caused and the weird stories that came out of it just by word of mouth gave it an aura of mysterious wonder that made the television industry infinitely more fascinating than it already was.

It also spawned a pretty decent made-for-TV HBO movie. Now I don't know what kind of craziness "Round Two" has to offer, but the players involved are definitely going to have all sorts of wild secrets revealed from Carter's work and when it does, HBO is going to want the movie rights. So here's who should play who in this new tragic merry-go-round of television programming hilarity that shall be called 'The Late Shift 2'.

While NBC is carefully plotting Jay Leno's exit from The Tonight Show, David Letterman is talking about staying on the CBS Late Show beyond 2010. And since the subject of Leno came up, Dave thinks the guys at NBC are nuts to treat Jay the way they are, especially since he's done such a great job in the 11:30 slot. Letterman even said he wants Jay on his show the day after his Tonight Show tenure ends.

Letterman, who was once the heir apparent to Johnny Carson's desk but was passed over in favor of Leno, has thrived on CBS even though he was crushed to lose The Tonight Show. The supposed feud between Letterman and Leno, and their competition for The Tonight Show, was depicted in the HBO film (and Bill Carter book) The Late Shift. (If you've never seen it, buy or rent it; it's one of the best films ever about how TV works behind the scenes.)
