Doctor Who
The Tenth, Eleventh, and War Doctors met each other in the 50th anniversary special on November 23, 2013. That was the first time the War Doctor was seen. That special had short appearances by all the other Doctors with the use of old, recycled footage. It also had a mysterious version of the Doctor from the far off future played by Tom Baker. The Eighth Doctor also made a return in 2013 for a 50th anniversary special mini-episode.
