Captain John Hart, played by James Marsters, is a fictional character from the BBC science fiction television programme Torchwood. He is introduced in the episode "Kiss Kiss, Bang Bang"—the first episode of Torchwood's second series. Whilst the character has not featured subsequently to the second series finale, he went on to appear in a Torchwood Magazine comic strip and Marsters has stated his interest in reprising the role on more than one occasion.
In his first appearance, John Hart is as a rogue Time Agent and former partner of the series' lead male character Jack Harkness (John Barrowman) both professionally and sexually. Whilst the original function of the Time Agency—stated to have ceased operation by the time Hart appears —is left unspecified, John's own backstory is briefly given: as well as having had a relationship with Jack, he has been in rehab for an addiction to alcohol, drugs, sex and murder. John leaves Earth disgraced after his initial self-interested plot is foiled by Harkness' Torchwood team, though returns in the series finale "Exit Wounds" where he is eventually given a chance to redeem himself.
The role of John Hart in Torchwood was written with the casting of Marsters in mind after he contacted the shows' producers expressing his interest in appearing in the programme's parent show, Doctor Who. The character is used to illuminate some of Jack's own characteristics as a doppelgänger who provides both an exaggerated version of, and a parallel to, aspects of Jack's persona. Both Marsters and the general media also compared aspects of Hart's character to Marsters's role as Spike in Buffy the Vampire Slayer and Angel. Whilst a few reviewers criticised the character in relation to his impact of the show's tone, a larger number welcomed the character and the energy Marsters brought to the role.
