Who to play 'Who'?


LONDON -- The BBC is refusing to deny press reports that "Doctor Who" star David Tennant will leave the show after the current season completes filming.

A spokeswoman for the pubcaster said Thursday that the star was "totally committed" to the current series of the show, but said it was "too early to say" whether Tennant would work on a fourth season of the revamped sci-fi cult hit.

"He is totally committed to filming the third series, which goes on air next spring, but it's too early to say anything about any future series," a BBC spokeswoman said. "I don't think a fourth series has even been commissioned yet, although there probably will be one."

British tabloid newspaper the Sun reported that Tennant plans to quit next year.

Tennant, who took over the role from Christopher Ecclestone in 2005, was recently voted the best actor to have played the time-traveling spacelord in a poll of 4,000 readers of the "Doctor Who" magazine.
