Guess who's coming to American TV?

David Motherfucking Tennant!!!!!!!!!!!!!!!!!!!

'Doctor Who' star lands 'Rex' pilot

No longer will American TV audiences be asking doctor who?

Popular British actor David Tennant, best known for playing the title role in the BBC's long-running sci-fi series "Doctor Who," is set to make his American television debut as the title character in NBC's hourlong pilot "Rex Is Not Your Lawyer."

Written by Andrew Leeds and David Lampson, "Rex" centers on Rex Alexander (Tennant), a top Chicago litigator who begins suffering panic attacks and takes up coaching clients to represent themselves in court.

David Semel, who directed the pilots for "Heroes" and "Life," has come on board to helm the comedic legal drama from Universal Media Studios and BermanBraun.

He will also executive produce with veteran Barry Schindel (who is attached as showrunner), Gail Berman, Lloyd Braun and Gene Stein. Leeds and Lampson serve as supervising producers.

NBC greenlighted the project in August, about two years after it was first developed, and had been trying to find a lead actor for several months until Tennant came along and nailed the part.

Tennant, a theater and TV actor, rose to fame playing the mysterious alien time-traveler at the center of "Doctor Who" for the past five years. His performance as the Doctor has been often rated as the top in the franchise's 46-year history.

Tennant's casting is reminiscent of the tapping of another established British TV actor with virtually no American TV experience, Hugh Laurie, as the lead on Fox's medical drama "House."

Tennant, who co-starred in "Harry Potter and the Goblet of Fire," recently signed with UTA. He's also repped by U.K.'s Independent Talent Group.
