DAVID TENNANT will quit hit British TV show DOCTOR WHO in a bid to pursue a career in Hollywood.
Tennant, 36, who made his first outing as the infamous Time Lord in December 2005, will allegedly quit the show next year (08).
According to reports, he will be replaced by John Simm, 35, star of 1999 cult British film Human Traffic.
A source tells British newspaper News Of The World, "John (Simm) is absolutely over the moon.
"He's got a six-year-old son who is a massive Doctor Who fan and he can't believe his dad is going to get to fly the Tardis at work." And Simm is no stranger to the sci-fi series - he already starred in three episodes of the show earlier this year (07), as Doctor Who's nemesis, The Master.
