The third Geordie is Dennis (Tim Healy), a bricklayer who, being older, more experienced and generally more mature than the others, becomes the de facto leader of the group. The others are Bristolian bricklayer Bomber (Pat Roach) and Scouse ex-con plasterer Moxey (Fairbank). Over the course of 13 episodes the "Magnificent Seven" enjoy comic, dramatic, and romantic adventures, until a change in German tax laws forces them to return home. The "building site" used for most of the filming was a set created on the backlot of the former ATV studios at Borehamwood (then owned by Central) and sometimes referred to as one of the Elstree Studios in Hertfordshire. After its sale to the BBC in 1984, the "Albert Square" set of "EastEnders" was later built there. Such was the attention to detail that the producers imported thousands of bricks from West Germany as these were slightly bigger than those used on British building sites. The show was one of the first to use lightweight video cameras on location in drama production. Previously used in Electronic News Gathering they were more versatile and cheaper to use than studio-based cameras. Interior scenes (such as those in the bar) were shot in studios at Borehamwood. Some location filming was conducted in Hamburg, despite the fact that the series was set in Düsseldorf. In these scenes most of the cars' registration numbers begin with HH denoting Hamburg (HH = Hansestadt Hamburg). The location sequences in Hamburg and Düsseldorf actually only lasted 10 days. The Intercontinental hotel which Dennis, Wayne and Barry visit in episode 7 titled Private Lives, was the same hotel in which the cast and crew stayed while filming there. In the last episode of the series, "When The Boat Goes Out", the hut on the site where the gang live accidentally catches fire and burns down. The ruins shown on the end credits were the actual ruins of the hut that was used for filming. In 2000, the first series was ranked #46 on the 100 Greatest British Television Programmes, in a list compiled by the British Film Institute. It is the only series of the show to make the list. The second series of 13 episodes in 1986 saw the boys reunited, initially to help Barry complete extensive building work on his new home in Wolverhampton. Dennis is working for a crooked businessman, Ally Fraser (played by Bill Paterson), to whom he owes money.
