The BBC's Doctor Who website has announced that an animated Doctor Who cartoon is being produced, to air as part of Totally Doctor Who next year. David Tennant andFreema Agyeman will voice the Doctor and Martha in the animated story, and Anthony Head will play Baltazar, Scourge of the Galaxy (not Mr. Finch from "School Reunion"). Toby Longworth (who has played many roles for Big Finish Productions' line of audio dramas) will also appear.
The cartoon will have 13 parts, comprising a single story titled "Infinite Quest". Russell T Davies describes the story: "The Doctor and Martha follow a trail of clues across wild and wonderful alien worlds, to find the location of the legendary lost spaceship, the Infinite." The story is written by Alan Barnes and directed by Gary Russell.
