Watts family
When "EastEnders" began in 1985, the soap focused primarily around the affairs of three families: the Beales, Fowlers, and Watts. However, much of the show's early success stemmed from the drama surrounding the Watts, especially the antics of Den, who as owners of the Queen Vic pub (the show's most prominent set) were usually in the limelight. This prominence, at a time when "EastEnders" was at its most prolific in terms of both the media and audience, meant the Watts became perhaps "EastEnders" most eminent family and the characters known even to those who did not watch the show. Such was their success that producers went ahead with an experimental episode format centring on just Den and Angie, during which Angie lied about having cancer; so successful was the airing that it has since been repeated, and the format expanded to include "three" and "four-handers" (between 3 and 4 characters). Such episodes are highly prestigious and feature only the most popular and prominent characters in the show; thus, all the Watts, aside from Vicki, have featured in such episodes.
Pam St Clement
In 1986 St Clement was cast in her most notable role to date—Pat Wicks, the troublesome former prostitute and ex-wife of Pete Beale (Peter Dean), in BBC's "EastEnders" (the show's producers wrote that the marriage had taken place more than 20 years before EastEnders was launched). She played the character continuously since her first appearance on 12 June 1986 – just over a year after the show began. St Clement's character was originally brought in on a trial basis for a period of three episodes. However the series' executive-producer, Julia Smith, decided to introduce her as a regular character. St Clement initially had reservations about committing to the role, commenting: "I couldn't envisage how this character, who creates absolute havoc everywhere she goes and is not at home with herself or with anybody else in the Square, could possibly fit in". However she was persuaded to continue by Smith, who said: "'We've only seen one layer of the onion skin—the defensiveness—now we'll start to peel away more and get to the vulnerability that lies behind it'." Pat went on to become one of the soap's longest running characters, appearing in 2,183 episodes.
