FYI, it’s 2059, for those playing along at home. The Earth has its first off-world colony. That’s the good news. The bad news is that the planet is also inhabited by aliens that use a water compound to infect victims. The really bad news is that this marks the beginning of the end of David Tennant’s reign as Doctor Who.

Sunday, November 15 on BBC One

The first of the remaining three episodes in the life of David Tennant as Doctor Who is set to premiere on BBC One, Sunday, November 15. The remaining two episodes will air as a two-parter, The End of Time, and will feature David Tennant’s Doctor regenerate into Matt Smith’s Doctor. Part one will air on Christmas Day in the UK while part two is expected to air on or around New Years Day.

For those of us on this side of the pond, unfortunately, we’ll have to wait a bit for this to get to America. Hopefully, this trailer will tide you over until it makes its’ way to the U.S.
