It seems one popular British series will be searching for a new lead in 2010. According to Yahoo, Doctor Who's David Tennant is leaving the beloved BBC series after 2010.

Tennant will portray the title character for a Christmas episode and four additional hour-long episodes in 2009 and early 2010. However, the actor said that when the series returns for a full season in 2010, "it won't be with me."

"This show has been so special to me," Tennant said. "I don't want to outstay my welcome."
