So, it would appear that Jimmy Fallon has Conan O'Brien's old (current?) job when Conan moves to be Jay Leno's replacement in 2009. I suppose there is a conservation of low-wattage comedians law in effect over at NBC's Late Night division.
I'm waiting for Dick Cavett to weigh in on this on his blog, which is excellent, by the way. The logic here doesn't really make much sense to me. My guess was that J-Fal (you know his asshole buddies call him that) got this based largely on his tenure on Weekend Update, as opposed to his film career or his famous poker face. To be fair, Jon Stewart had a pretty terrible film career and he's doing alright in his current job. Then again, Jon Stewart is, well, funny. And professional. For all his virtues, Stewart really isn't much of an actor--I recall watching a NewsRadio episode in which he was a guest star and his performance there contained so much discomfort that it might have been better suited to playing a teenager losing his virginity. I did like his self-portrayal on The Larry Sanders Show, and that's about it. But--and here's the difference--Stewart can talk to people. The Daily Show isn't really a chat show, but the chat segments are usually solid, if light. Now, if Fallon were being considered for Stewart's job, I'd say that makes sense, although I always thought his version of Weekend Update was a bit overrated--to think that someone's fake news could actually make me miss Craig Kilborn!--but he was alright.
Fallon, though, got Conan O'Brien's job. I've long believed that Conan was at his best during interviews and at his worst during the monologues, and his sketches have always been entertaining. I'm not exactly sure what Fallon would do for a whole hour--I'm guessing a lot of sub-Sandler singing and giggly, passable impersonations, perhaps with Horatio Sanz as a sidekick (as if!)--but I've never thought him interesting enough to look at for more than a few minutes, and this whole thing reeks of bean counters trying to tap the "youth" demographic. Hey, guys, newsflash: we young people don't really like Jimmy Fallon too much. If we did, we would have seen his movies. He was occasionally amusing on Saturday Night Live. That's it.
Who knows, maybe Fallon will prove quite adept at the host's chair, but the chatting part of the equation is unknown at this point, unless you count The Barry Gibb Talk Show, and I doubt Timberlake is going to want to co-host. And isn't that, like, the most important part of the show?
