'Prison Break,' 'Rosie,' 'Enemy' update

-- Rumblings of the primetime apocalypse continue: THR reports that the end could be near for "Prison Break."

-- With "My Own Worst Enemy" departing, fans keep e-mailing about the recent pickup of "Knight Rider" -- pointing out that it has a lower rating than "Enemy." Yeah, sure, but what are you gonna do? NBC made the pickup decision when "Rider" had a 2.4, and is doing its best to improve the show. 

-- What series will go in the "Enemy" slot? No word yet. "Enemy" is still airing Monday. Fans are guessing "Medium," which is a good guess. "Kings" would be ideal for the post-"Heroes" slot, but NBC probably doesn't want to launch it right before the holidays.

-- NBC announced this morning that Kathy Griffin, Jane Krakowski and Alanis Morissette will appear on Rosie O'Donnell's upcoming NBC variety special "Rosie Live" on Nov. 26. It's like some ill-conceived "Saturday Night Live" skit about a faux cable network -- ShrewTV. It's tough to imagine a more intentionally grating collection of oft-bitter-acting personalities. To avoid seeming gender unbalanced, NBC should enlist Danny Bonaduce, Dane Cook and Joe Francis for an obnoxious male douchebag version. Given the recent performance of "Rider" in the slot, however, a failure by "Rosie" to improve the time period will be difficult.
