Some publicity has been given to the fact that Gridlock is the 727th episode of Doctor Who. This will break the record held by the various Star Trek series, which have a total of 726 combined episodes amongst them. Doctor Who has been recognised by the Guinness Book of World Records as the longest-running science fiction series in the world, based on the original series' 26-year continuous run and the 43+ years since the programme's 1963 debut.

Ein Grund zum Feiern? Aber sicher doch.
