Being the most successful sci-fi series ever isn’t enough for Doctor Who. The 50th anniversary special broke the simulcast record as it was broadcast in 94 countries at more than 1,500 movie theatres. It is now the world’s largest simulcast of a TV drama, according to the Guinness Book of World Records. More than half a million tickets were sold worldwide. “For years, the Doctor has been stopping everyone else from conquering the world. Now, just to show off, he’s gone and done it himself,” said series head writer Stephen Moffat.
