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.
Gillian Taylforth
On 19 February 1985, Taylforth appeared as Kathy Beale in the first episode of the BBC's new soap opera "EastEnders". This role earned her huge popularity and public recognition on British television. Taylforth's character was in the show from 1985 until 1998, when she opted to leave. Kathy made 2 guest appearances in 1999 and 2000. During her time on the show, Kathy covered an array of serious issues including rape, domestic violence, teenage pregnancy, divorce, alcoholism and meningitis. She became one of the longest running characters to feature in the soap, but eventually quit in 1998. She made a brief return in 1999 to aid the departure of actor Ross Kemp, who played her character's brother-in-law, Grant Mitchell before leaving again on 6 January 2000.
