It is believed the deal has been struck with global networks to prevent any spoilers and plot leaks, and is set to make it the world's biggest drama simulcast when it goes out on Saturday 23rd November.
In a statement, BBC Worldwide said:
It's always been our ambition to work with our broadcast partners so that international Doctor Who fans can enjoy the 50th-anniversary special at the same time as the UK. We'll have more details soon about our very exciting global plans for November.The episode, whose title is yet to be publicly announced, will be shown in both 2D and 3D.
The time differences around the world mean that an evening transmission in the UK on the Saturday would see it being shown earlier the same day in North America and early on Sunday 24th November in Australia and New Zealand.
