Spaced

Spaced was a British sit-com written by, and starring, Simon Pegg and Jessica Hynes (credited at the time as Jessica Stevenson).

The series contained references to many pop-culture and cult series' which included Doctor Who. Perhaps the most obvious is a door that is decorated to resemble the The Doctor's TARDIS. This is given more significance by the fact that the stockroom on the other side of the door is noticeably bigger than the shop floor from which it opens.

Connections with Invaders from Mars
Released just one year after the final series of Spaced was broadcast, the Eighth Doctor Big Finish audio drama Invaders from Mars has several connections with the series. Not only did it star both Pegg and Hynes alongside Spaced guest star Paul Putner, but it was also written and directed by another guest star, Mark Gatiss.

The two also share a thematic connection as they both deal with audience reactions to popular culture. While Spaced looks at the wider way that people assimilate pop-culture into their everyday lives, Invaders from Mars focuses on a singular real world event, in which audiences believed Orson Welles' radio adaptation of War of the Worlds was an actual alien invasion.

Other connections to the DWU
