This episode takes place in 1999.
The pilot would be remade and shown in 1986. Both are broadly the same although they are different in places. Bob (David Garlick) has far lighter colored hair and a different haircut in the pilot. The parts of Treen, Gran, the school teacher and black marketeer would be recast in the remark.
Anna Whig plays Gran in the pilot but by the time the show had gone to a series to be made in 1985, Whig had a regular part in EastEnders as Lou Beale which started in February 1985 and the part was recast with Doris Hare.
The pilot states that the revolution took place in 1987 but in the remake it is moved to 1989.
