The Lodger (Doctor Who)

"The Lodger" is the eleventh episode of the fifth series of the British science fiction television series Doctor Who, first broadcast on BBC One on 12 June 2010. It was written by Gareth Roberts, who based the story on his 2006 Doctor Who Magazine comic strip "The Lodger".

The episode features the Eleventh Doctor (Matt Smith) stranded on Earth and separated from his companion Amy Pond (Karen Gillan), when an unknown force prevents his time travelling spaceship, the TARDIS, from landing. To investigate, he moves into the flat of Craig Owens (James Corden) and attempts to fit in with ordinary humans while unknowingly playing matchmaker for Craig and his good friend Sophie (Daisy Haggard).

Showrunner Steven Moffat was a fan of Roberts' original comic strip and enthused him to adapt it into an episode for the series. While some elements of the comic strip remain, Roberts wrote most of it from scratch. "The Lodger" replaced a slot held by an episode that was pushed back due to budgetary constraints and was consequently one of the last to be filmed. The episode was watched by a final 6.44 million viewers, the least-watched episode of the fifth series of Doctor Who. However, it achieved the joint highest Appreciation Index of the series at the time of broadcast.
