David Tennant returned to Doctor Who as not the tenth, but the fourteenth Doctor.
Russell T. Davis also returned as showrunner for the three-anniversary special.
Nkuti Gatwa was introduced as the Fifteenth Doctor in a special broadcast in November 2023, followed by a Christmas special.
Tennant's Fourteenth Doctor is very similar to the Tenth, even acknowledging his predecessor.
This is Tennant's second time playing the Doctor, following his previous performance as the Tenth from 2005 to 2010.
Tennant's return creates excitement for possibilities beyond the established lore of the Tenth Doctor.
Fans speculate that the Master's forced regeneration may have affected the Doctor's process.
Others suggest that the Thirteenth Doctor's reversal of the Master's control brought about a familiar face.
The 60th anniversary special promises an exciting return to form for David Tennant and Doctor Who.
