The British actor David Tennant is a graduate of the Royal Scottish Academy of Music and Drama whose background includes the Royal Shakespeare Company and numerous BBC television productions. Tennant joined the BBC series Doctor Who in 2005 and announced that he will leave the show after shooting four episodes for 2009. On January 3, 2009, the BBC announced that relative newcomer Matt Smith will be replacing him in the role.UK Telegraph: Matt Smith New Doctor Who (January 3, 2008)

On April 18, 2005, Tennant was announced as the tenth actor to play The Doctor in the perennial BBC series, Doctor Who, to replace the short-lived Christopher Eccleston. The choice of the youthful Tennant continued a slow, decades-spanning trend in the show toward casting ever-younger actors in the lead role, which was originated in 1963 as that of an elderly man. He played the role of the tenth Doctor until January 1, 2010.

Tennant also played the character Barty Crouch, Jr., in the November, 2005 release, Harry Potter and the Goblet of Fire.

Tennant has extensive experience in stage work, appearing with the Royal Shakespeare Company in productions of As You Like It, Comedy of Errors, The Rivals, and Romeo and Juliet.

In something of a startling upset, a 1996 poll in Doctor Who Magazine voted Tennant as the Best Doctor, despite traditionally rabid partisanship among American fans toward the Fourth Doctor, Tom Baker, and among British fans toward the Third Doctor, Jon Pertwee.
