Channel Surfing: Tamsin Greig Lands Episodes, Steve Carell Looks to Leave The Office, History Casts The Kennedys, and More

Welcome to your Thursday morning television briefing.

Cast changes are afoot at Showtime's upcoming Matt LeBlanc-led comedy Episodes, with Thomas Haden Church pulling out of the project due to a scheduling conflict with a film and Claire Forlani being recast after the recent table read earlier this week. But with Forlani out, Showtime has had the luck of landing British actress Tamsin Greig (Black Books, Green Wing, Love Soup) to replace her. [Editor: I think Greig is a much better fit and is a comedy genius. Showtime is beyond lucky to have nabbed her. Grieg's Black Books character, Fran Katzenjammer, remains a perennial favorite.] Greig will step into Forlani's role, as the female half of a husband-and-wife writing team whose British series is adapted for American television... and ruined in the process. Showtime has ordered seven episodes of the series, which is created by David Crane and Jeffrey Klarik, who executive produce alongside Jimmy Mulville. (Variety)

Steve Carell has announced his intention to leave The Office after one more season. Speaking to BBC Radio 2's Steve Wright, Carell said that his contract with the Universal Media Studios-produced comedy goes "through next year" and then went on to say, "I think it will probably be my last year." NBC isn't commenting though it's thought likely that The Office wouldn't continue without Carell on board as Michael Scott. [Editor: in fact, it's the perfect opportunity to wrap up the series.] "This could be a negotiating ploy, but honestly, I don't think so in this case," an unnamed insider told E! Online's Megan Masters. (Office Tally via E! Online's Watch with Kristin)

History Channel has unveiled the cast for its upcoming eight-hour controversial miniseries The Kennedys, which will star Greg Kinnear, Katie Holmes (as Jacqueline Kennedy, no less!), Barry Pepper, and Tom Wilkinson. Project, which will air in 2011, is executive produced by Joel Surnow, Jonathan Koch, and Steve Michaels, with Steve Kronish writing and Jon Cassar directing. The mini will dramatize the "the personal relationships between the Kennedy clan -- including John's and Bobby's tumultuous relationship with their father," according to Variety's Michael Schneider.

Ricky Gervais will once again host NBC's Golden Globes telecast, the network has announced. Despite the fact that the 68th Annual Golden Globes don't air until next January, NBC took the unusual step of announcing that Gervais would return... nine months ahead of broadcast. "I can't believe they invited me back after awful things I said," said Gervais in a statement. "Let's see how far I can go this time." NBC's Paul Telegdy, meanwhile, compared Gervais to an unstoppable force of nature. "As viewers discovered with our last awards telecast, Ricky's surprising and unpredictable humor is a great fit for the Globes which will continue as a live event across the nation," said Telegdy. "He's a true force of nature with a wicked sense of humor who always keeps everyone on their toes waiting for the unexpected."(Hollywood Reporter)

SPOILER! Don't expect any sense of closure for Katherine Heigl's character on ABC's Grey's Anatomy, according to series creator Shonda Rhimes. "It’s going to linger," Rhimes told Entertainment Weekly's Michael Ausiello. "And I actually feel good about it lingering because [it means] Alex is left with unfinished business. And that’s going to be very interesting for his character." Meanwhile, Rhimes isn't spilling about the game-changing season finale for Greys. "The events of the finale itself change the game," she told Ausiello. "Whether anyone lives or anyone dies is not really necessarily the point of it." (Entertainment Weekly's Ausiello Files)

Salary negotiations are set to get underway for four cast members on CBS' NCIS, including Michael Weatherly, Pauley Perrette, David McCallum, and Sean Murray, each of whom are looking to increase their episodic paycheck before the series returns in the fall for its eighth season. "The real question is how much CBS is willing to pay the four stars moving forward: Deadline.com is reporting that the company dangled low-ball offers, which stalled negotiations," writes Entertainment Weekly's Lynette Rice.
