Channel Surfing: ABC Picks Up Tab for "Private Practice," Showtime Keeps "Dexter" Killing, Bomer and DeKay Try On "White Collar," Tony Hale, and More

Welcome to your Wednesday morning television briefing. I'm still on cloud nine after last night's perfect combination of sweet and tart on BBC America's Gavin & Stacey. Could that series be any funnier or any more genuinely emotional? It's well lush.

Looks like Kate Walsh won't be returning to Seattle Grace any time soon. ABC has picked up Grey's Anatomy spinoff Private Practice for a full season of 22 episodes. Series, which had its freshman season truncated due to the writers strike, has averaged 3.2/8 in adults 18-49 and 8.3 million viewers across two original episodes this fall. (Variety)

Showtime wants more Dexter: the pay cabler announced that it had renewed the serial killer drama for two additional seasons (that would be Season Four and Season Five) of twelve episodes each. Production on Season Four will begin in Los Angeles next spring. (Hollywood Reporter)

CBS has ordered two additional scripts for freshman comedy Worst Week, which--after premiering to some dismal numbers--has remained steady in the ratings with a 3.2/7 among adults 18-49 and 9.9 million viewers overall. (Yep, Worst Week is doing better than Private Practice, folks.) (TV Week)

Tim DeKay (Carnivale, Tell Me You Love Me) has been cast as the lead of USA's 90-minute drama pilot White Collar, opposite Matthew Bomer. DeKay's attachment lifts the cast contingency on the project, which will be directed by Bronwen Hughes (Burn Notice) and comes from Fox TV Studios and writer/executive producer Jeff Eastin. (Hollywood Reporter)

In other casting news, Gina Torres (Standoff, Dirty Sexy Money), Brett Davern (American Summer), Scott Cohen (The Return of Jezebel James), Sammi Hanratty (American Girl), and Jen Drohan have been cast in Lifetime's drama pilot The Amazing Mrs. Novak. (Hollywood Reporter)

Tony Hale (Arrested Development, Chuck) and newcomer Ben Koldyke (Thirteen Days) have been cast in FOX comedy pilot Boldly Going Nowhere, from the It's Always Sunny in Philadelphia boys. Koldyke will play a rogue spaceship captain in this high-concept comedy that looks at the lives of the ship's crewmembers between intergalactic missions. Hale will play the ship's put-upon robot. (Hollywood Reporter)

CBS Paramount has signed a first-look deal with comedy troupe Second City Entertainment; under the deal, the studio will have a crack at the troupe's performer/writers who will workshop potential projects for pilot consideration. (Variety)

Rosie O'Donnell will star in and executive produce telepic America for Lifetime, about a 16-year-old boy who struggles within the foster care system. (Variety)

Stay tuned.
