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.
John Altman (actor)
In 1985, he first appeared as Nick Cotton in the new BBC television soap opera "EastEnders", appearing in the very first episode in February that year. He went onto make recurring appearances in the show and has been part of many famous storylines in the show including the murders of Reg Cox (whose body was found in the very first episode) and Eddie Royle, his attempt to kill his own mother Dot by poisoning her and his various feuds with characters like Pete Beale, Den Watts and Mark Fowler. 
His character was also given his own television spin-off episode titled "Return of Nick Cotton" which aired in October 2000. His character was killed off in the episode that aired on 13 February 2015 and made his final appearance as a corpse in the episode that marked the 30th anniversary of the show on 19 February 2015. His body was found in the same way as his victim Reg Cox was found in the very first episode. A year earlier, his character's death had been announced in the show, only for it to emerge within a few months that Nick had faked his own death.
