Doctor Who fans across the globe eagerly await the return of David Tennant as the Fourteenth Doctor to celebrate the show's 60th Anniversary. Another science fiction franchise about to celebrate six decades of crossing time and space is Star Trek, currently in its third wave of new shows. Doctor Who and Star Trek missed each other by months the first time Russell T Davies was in charge, but perhaps now he can get that crossover he wanted. Along with their shared longevity, Doctor Who and Star Trek have a lot in common despite being built around wildly different premises. The British sci-fi series started as a show for children meant to combine historical lessons with fantastic adventure.
