10 Unmade Doctor Who Stories We Wish We'd Seen

Peter Harness, who co-wrote the dark urban thriller The Zygon Inversion/Invasion with Steven Moffat pitched another story that was much lighter. The story was to feature the return of a renegade Timelord last seen in the 1960s, the Monk. Originally played by comedy actor Peter Butterworth, Harness envisioned Matt Berry in the role.

The plot was to feature the meddlesome Timelord calling the Twelfth Doctor for help when he accidentally averts the Russian Revolution by playing Boney M to Rasputin. They then try to set history back on course, with the Monk eventually taking on Rasputin's identity. It's a mad, comic idea but it might have just worked. One can only imagine what a brilliant comedy double act Capaldi and Berry would have made.

Moffat turned down the pitch and Harness' next story for the series was the underwhelming Pyramid at the End of the World. Watching a blind Doctor trying to crack an entry code is nowhere near as much fun as him mucking around with Rasputin, Matt Berry and the music of Boney M.
