Doctor Who: 10 Historical Figures That Need To Be Explored
10. David Bowie
This might seem like a strange choice, but it would be interesting to see the show take on a more recent historical figure, and break the mold with a musician - something a little different. Bowie often tops lists of dream castings for The Doctor, and it's not difficult to see why - he has a certain quirky, unearthly quality that would lend itself very well to the show.
In fact, Eleven once traveled with character called Jones in the Titan Comics range (Jones was essentially a royalty-free Bowie, a way to insert the famous popstar without having to directly acknowledge what they were doing), and his run as a companion in that series is evidence enough that this would work, in its own totally weird way.
This is a historical figure that would better suit being dropped into a futuristic or space-based episode as a one-time companion, rather than a historical, so that we could see him in his element, and witness the events that would go on to inspire him to write the likes of Space Oddity and particularly Starman, which feels as if it's written for a certain time-travelling hero.
You could adapt one of The Doctor and Jones' stories to the screen, here. The SERVEYOUInc story arc, in which The Doctor and company face off against a creativity-stifling galactic corporation and a demonic talent scout by playing them at their own game, is a popular choice (especially given, without spoiling too much, it could give the character of Bowie the opportunity to take over The Doctor's role, even briefly).
