Therefore, its known narrative elements are not a part of the Doctor Who universe as we, on this Wiki, choose to define it. It may have been the basis for a similar story in another medium, however — and that story may indeed be valid.
Don't Shoot, I'm the Doctor! was a story concept in John Leekley's series bible for Amblin Entertainment's proposed 1990s Doctor Who television show. The story was intended to be a "more historically accurate" version of the First Doctor serial The Gunfighters.
Of the stories in the Leekley Bible, this was the only one to undergo significant development. The feud between the Earps and the Clantons was intended to contrast the state of Gallifrey after the rise to power of the Doctor's half-brother, the Master. Leekley hoped the movies Silverado and Back To The Future Part III would serve as the episode's visual inspirations.
While travelling through time and space, the Doctor gets a severe toothache. He decides he'll set coordinates for the Blue Planet Earth, where he knows he can get help. However, an error in his calculations sets the Tardis down in Tombstone on 26th October, 1881.
The only doctor available is none other than the infamous gunslinger, Doc Holliday, who is feuding with the Clanton family. Both doctors strap on their guns to help Wyatt Earp against the bushwacking Clantons in the shoot-out at the OK Corral.

Suffering from a severe toothache, the Doctor sets course for Earth but erroneously arrives in Tombstone on 26 October 1881. There he meets Doc Holliday and his wife Kate. Holiday is abusive physically towards Kate. The Doctor and Kate begin to fall for each other, and Kate implores the Doctor to intervene in a growing feud which pits Holliday and the Earp brothers against the Clanton gang. The Doctor is mistaken for Holiday on night and attacked by Ike Clanton. In the chaos, Ike later escapes as the Clanton gang come to town, and the Doctor decides to get involved to prevent Holliday from killing Clanton when an innocent prisoner is shot dead. Holliday attacks the Doctor in a rage. In the chaos of the brawl, Holliday is knocked unconscious and the Doctor's bad tooth is knocked out. The Doctor then escapes in the TARDIS.
- Leekley incorporated a subplot about Lester Moore, who was the owner of the most famous epitaph in the Boothill Graveyard at Tombstone. The story would have "revealed" this to have been in fact conceived by the Doctor himself.
- Leekley, a fan of the Wild West, hoped the setting would appeal to American market as one of the few "big pieces" of American history.
