Is this the one where Joey gets his really big break? Maybe so. Sources say talks are accelerating among NBC, Warner Bros. TV and Matt LeBlanc to cut a deal for a "Friends" spinoff sitcom revolving around LeBlanc's Joey Tribbiani character. Sources stressed that no deals are in place for the spinoff, but it's understood that the principals have stepped up the negotiations in an effort to secure a commitment with LeBlanc in the near future. Sources say that those players also have settled on veteran "Friends" scribes and executive producers Scott Silveri and Shana Goldberg-Meehan to pen the pilot script should a deal be hammered out. LeBlanc's character of the oddball soap opera actor has, of course, been at the center of "Friends" during the past two seasons as the love triangle played out among Joey, David Schwimmer's Ross and Jennifer Aniston's Rachel characters. And LeBlanc's bargaining power certainly wasn't hurt by the fact that the actor last week earned his second consecutive Emmy nomination for his work on America's most-watched comedy series. NBC and Warner Bros. TV declined to comment.
