Diane Keaton is planning an American remake of British TV drama Last Tango In Halifax. The Annie Hall star has acquired the rights to the BBC romantic drama and will shoot a U.S. version for cable TV channel HBO. The original programme, about two 70-year-olds rekindling a childhood romance via Facebook, stars Derek Jacobi and Anne Reid, but it is unclear if 67-year-old Keaton plans to take a role in the remake herself. The drama's writer Sally Wainwright broke the news during a Broadcasting Press Guild lunch in London on Monday (28Oct13) and confirmed she will have an associate producer role in the remake but does not expect to be closely involved. Last Tango in Halifax was one of the BBC's best performing new shows of 2012 and a second series is set to start in the U.K. next month (Nov13) with a third already planned.
