EastEnders
"EastEnders" is often filmed on location, away from the studios in Borehamwood. Sometimes an entire quartet is filmed on location, which has a practical function and are the result of "EastEnders" making a "double bank", when an extra week's worth of episodes are recorded at the same time as the regular schedule, enabling the production of the programme to stop for a two-week break at Christmas. These episodes often air in late June or early July and again in late October or early November. The first time this happened was in December 1985 when Pauline (Wendy Richard) and Arthur Fowler (Bill Treacher) travelled to the Southend-on-Sea to find their son Mark, who had run away from home. In 1986, "EastEnders" filmed overseas for the first time, in Venice, and this was also the first time it was not filmed on videotape, as a union rule at the time prevented producers taking a video crew abroad and a film crew had to be used instead. In 2011, it was reported that eight per cent of the series is filmed on location.
EastEnders in popular culture
A charity special crossover between the science fiction television series "Doctor Who" and "EastEnders", "Dimensions in Time", was filmed in 1993 for Children in Need and ran in two parts on 26 November and 27 November 1993. It has been proven as non-canon by various references of "Doctor Who" as fiction in "EastEnders", and vice versa. "EastEnders" has participated in numerous other Children in Need and other fundraisers.
Characters have also been spoofed in the successful BBC comedy sketch show, "The Real McCoy" (1991–1995). "EastEnders" and its characters were frequently spoofed in the impressionist sketch show "Big Impression", starring Alistair McGowan and Ronni Ancona. "Big Impression" once screened a one-off special, focusing on "EastEnders", called "Alistair McGowan's BigEnders". The cartoon sketch show "2DTV" has also spoofed "EastEnders" on many occasions.
