<Ul> <Li> Trigger (Roger Lloyd - Pack)--Trigger, apparently so called because he looks like a horse, was the principal supporting character earlier in the show's run, although his importance lessened as the series progressed . Lloyd Pack was cast by pure chance: Ray Butt, who hired him to portray Trigger after seeing him in a stage play, had only attended that play to observe potential Del Boy actor Billy Murray . A daft road sweeper most frequently seen in the Nag's Head, Trigger was initially portrayed as a small - time thief, supplying Del with dubious goods . In later episodes he came to adopt the' village idiot' role, and believes that Rodney's real name is Dave . </Li> <Li> Boycie (John Challis)--A shady used car salesman and a frightful snob . Boycie, a freemason, was very self - centred and prone to boasting about his high social status . Challis had played a similar character in an episode of Citizen Smith . Sullivan liked him, and promised to cast him in a future series, which led to Boycie . Boycie later featured in a spin - off series, The Green Green Grass, starting in 2005, in which he and his wife Marlene fled from a criminal gang . </Li> <Li> Raquel Turner (Tessa Peake - Jones)--Raquel was introduced because Sullivan wanted more female characters and for Del to start meeting more mature women . Her first appearance, in "Dates", was intended to be a one - off, but she was written in again a year later and thereafter became a permanent cast member . An ambitious trained singer and actress whose career never took off, she met Del through a dating agency, but they fell out over her part - time job as a stripper, before getting together again . This time she moved in with Del, helping to mellow him, and they had a son together, named Damien . As the character unfolded, it was revealed that she was previously married to Del's nemesis, DCI Roy Slater . </Li> <Li> Cassandra Trotter (Gwyneth Strong)--Cassandra first met Rodney in "Yuppy Love". Their relationship blossomed, and by the end of series six the two had married . But her high career ambitions caused conflict with Rodney, and their troubled marriage was one of the main storylines later in the show's run . </Li> <Li> Marlene Boyce (Sue Holderness)--Marlene was initially just an unseen character, occasionally mentioned by her husband, Boycie . She was a cheerful woman who desired a child . Details were occasionally revealed about Marlene's prior reputation as being popular with the local men . She did finally have a son, Tyler . </Li> <Li> Denzil Tulser (Paul Barber)--An easy - going Liverpudlian lorry driver, Denzil was often on the receiving end of Del's scams . His inability to say no to Del's business deals frequently led to conflict with his domineering wife, Corrine (Eva Mottley), who was only sighted once, in "Who's a Pretty Boy?". Sullivan had planned to bring Corrine back for more episodes, but after Mottley's death in 1985, he opted to make her an unseen character rather than use another actress . </Li> <Li> Mickey Pearce (Patrick Murray)--Mickey was a young, obnoxious spiv and friend of Rodney's, known for his exaggerated boasts about his success in business or with women . Despite their friendship, Mickey often took advantage of Rodney's gullibility by stealing his girlfriends or making off with all the money from their business partnership . </Li> <Li> Mike Fisher (Kenneth MacDonald)--The landlord of the Nag's Head, although not from the very beginning; his predecessor was never seen, with just a succession of barmaids providing service . Good natured and somewhat gullible, he was often targeted by Del as a potential customer for any goods he was selling . When Kenneth MacDonald died in 2001, a storyline involving Mike's imprisonment for attempting to embezzle the brewery was written, and cafe owner Sid took over as interim pub landlord . </Li> <Li> Damien Trotter (various)--Damien was Del and Raquel's son . It was Rodney's mocking suggestion that he be named Damien . Six actors played Damien: Patrick McManus (1991), Grant Stevens (1991), Robert Liddement (1992), Jamie Smith (1993--96), Douglas Hodge (1996, as adult), and Ben Smith (2001--03). </Li> <Li> Sid (Roy Heather)--Sid made sporadic appearances throughout the show's run, mainly as the proprietor of the run - down and unhygienic local cafe . Sid fought in the war and it is revealed in the episode "The Jolly Boys' Outing" that he was captured and imprisoned . After Nag's Head landlord Mike was imprisoned, Sid took over and kept that role for the remainder of the series . </Li> </Ul> <Li> Trigger (Roger Lloyd - Pack)--Trigger, apparently so called because he looks like a horse, was the principal supporting character earlier in the show's run, although his importance lessened as the series progressed .
