In 2000, Tennant appeared at the Royal National Theatre, London, playing the role of Nicholas Beckett in Joe Orton's What the Butler Saw. The plot required Tennant to appear near-naked on stage.

Behind the scenes

 * Coincidentally, the last chapter that Tennant's Crouch Jr. appears in The Goblet of Fire is called "The Parting of the Ways" - as is the Doctor Who revival Series 1 finale where Eccleston's Ninth Doctor regenerates into Tennant's Tenth Doctor. The amount of time the characters appear in is also very similar, as Crouch Jr. appears for just the first page of the chapter, while the Tenth Doctor appears in the final scene of the episode.
 * Tennant's first true solo appearance as the Tenth Doctor occurred in a (canonical) mini-episode entitled Born Again in some circles, set immediately after his regeneration and produced for the 2005 Children in Need Appeal. This episode was first broadcast on 18 November 2005—the same day Harry Potter and the Goblet of Fire was released in cinemas.
 * Tennant and Freema Agyeman (companion Martha Jones) mention Expelliarmus, J. K. Rowling and the seventh Harry Potter book in the Doctor Who episode The Shakespeare Code.
 * During the two-part Doctor Who story Rise of the Cybermen / The Age of Steel, he appears along with Roger Lloyd-Pack - who in Goblet of Fire, appeared as Barty Crouch Sr. Ironically, their roles from Goblet of Fire are reversed in the episode, as Lloyd-Pack is a hero in Goblet of Fire but a villain in Doctor Who while Tennant is a Goblet of Fire villain but the hero in Doctor Who.

Trivia

 * In 2013, IGN ranked Tennant as the best Doctor, along with the Daily Mail and Radio Times
 * His wife Georgia (neé Moffett) is the daughter of Fifth Doctor Peter Davison.
