List of The Sarah Jane Adventures serials

The Wedding of Sarah Jane Smith is the third serial of the third series the British science fiction television series The Sarah Jane Adventures. The two-part story was first broadcast on BBC One on 29 and 30 October 2009. It guest stars David Tennant as the Tenth Doctor, marking the first appearance of parent programme Doctor Who's main character in a spin-off show. The episode includes the final scenes David Tennant recorded during his first tenure as the Doctor.[2]

In the story, alien investigator Sarah Jane Smith gets engaged to her boyfriend, Peter Dalton. However, alien time traveller and old friend of Sarah Jane's, the Doctor, raises an objection at her wedding, and the marriage is revealed to be a malicious plot set up by Sarah Jane's arch nemesis, the Trickster.


Peter Dalton, a servant of the Trickster, proposes to Sarah Jane. When Sarah Jane puts the engagement ring on it glows red and begins influencing her. At a countryside hotel two weeks later, the Tenth Doctor bursts through the doors, demanding the wedding be stopped. As he warns Sarah Jane to step away from Peter, the Trickster appears and kidnaps Sarah Jane.

As Luke, Clyde, and Rani regain consciousness, the Doctor introduces himself, swiftly revealing that they and K9 are the only people in the hotel; the Trickster has trapped them in a looping second, cutting them off from the rest of the world, and the TARDIS. The Doctor determines that Sarah Jane is trapped in another second, deducing that the Trickster has separated the group to prevent them helping Sarah Jane.

Peter is in a state where he is only half-alive. At the moment of his death, the Trickster offered him to be restored to life after he married Sarah Jane. The Trickster is holding Sarah Jane's friends hostage in a second, and time will only resume if she says "I do", after which she will forget her old life of defending Earth, creating more chaos for the Trickster to feed on.

The Doctor enters the TARDIS, with the hopes of using its artron energy to fight the Trickster. However, it departs before Luke, Clyde, and Rani can enter. Clyde's attempt to enter the TARDIS results in him becoming charged with artron energy, allowing him to attack the Trickster. With the Trickster's power momentarily disrupted by Clyde's attack, the Doctor is able to arrive in Sarah Jane's second, telling her that there is only one way to end the Trickster's deal. Sarah Jane informs Peter that the only way to stop the Trickster is for Peter to take back the deal, even though this will mean his death. Strengthened by his love for Sarah Jane, Peter ends the deal, returning the hotel to the moment before the Doctor's arrival. With Peter having vanished, Sarah Jane cancels the wedding. Returning to Sarah Jane's attic in the TARDIS, the Doctor says goodbye to Sarah Jane and her friends.

Cast notes

Zienia Merton had previously appeared as Ping Cho in the Doctor Who serial Marco Polo in 1964.[citation needed] Nigel Havers had previously played Nick in the Eighth Doctor audio drama No More Lies.[3]

In the story, Clyde states that Brigadier Lethbridge-Stewart is "back in Peru". It had been intended by the production team that Lethbridge-Stewart would appear in the story and meet the Tenth Doctor, but actor Nicholas Courtney was recovering from a stroke and unable to take part.[4]

This serial was the final episode that David Tennant filmed as the Tenth Doctor, as he had already finished filming The End of Time (his final chronological episode of Doctor Who) before production began on the serial. He would later reprise the role in the 50th anniversary special; and will play the Fourteenth Doctor in the forthcoming 60th anniversary specials in late 2023.[5]
