"Las Vegas" [1] is one of those shows that just seems to keep trucking along. The drama, which airs Friday nights, gets lost in the shuffle for me, but apparently it's doing well: NBC just renewed it for a fifth season. [2]

But in a weird twist, two of the show's stars won't be back [3]: James Caan (also known as The Godfather's Sonny Corleone) says he wants to get back into film, while Nikki Cox apparently got axed because of budget cuts [4]. Which seems odd for a show the network just decided to bring back, but hey, I don't pretend to understand Hollywood. Weirdly, both Caan and Cox were mentioned in NBC's press release [5] about the renewal. Don't they coordinate these things?

The good news: Breakout star Josh Duhamel is sticking around for now. And longtime fans, take note: TV Guide's Michael Ausiello reports that former "Las Vegas" star Marsha Thomason will turn up on "Lost" [6] later this season.
