In 1963, the BBC premiered a strange science fiction television show called Doctor Who. William Hartnell, then best known for portraying thugs and soldiers, played the title role. Now the longest-running science fiction show of all time and with fans around the world, the series celebrates its 50th anniversary with a special screening of The Day of the Doctor. The adventure teams Matt Smith’s Eleventh Doctor and his companion Clara Oswald (Jenna Coleman) with David Tennant, returning as the Tenth Doctor and his companion Rose Tyler (Billie Piper). Together they must face the darkest moment in The Doctor’s long, long life, when a previously unknown incarnation committed an unspeakable atrocity that dubbed him unworthy to bear the name Doctor. Expect tons of surprises and returning villains, including the Daleks and the Zygons, as well as trips to The Doctor’s home planet of Gallifrey.
