I remember watching some of this episode being filmed. The exterior shots of the main entrance of the laser quest building were filmed at the old Coronet Cinema that stood on Well Hall Roundabout in Eltham, South East London. It's now a gymnasium.
@119Mario - You're probably too young to remember Laser Quest! The backpacks/armour registered a hit with an opponent's laser. The idea was to make a king of electronic game of tag with real people in a real environment. Used to be thought as the future of computer games...LOL
Lukas LoopyLukas He died in Season 9 episode 5 after falling 80 ft from a gangplank in a warehouse that was filming a pop group music video, this is season 7 two years before. Some workman were working on the roof and one of them wasn’t keen on the boiler fumes coming from its vent so his friend stuck a girder down the stack which made the fumes go a different direction but down below the boilers pressure started to build up and overheat due to lack of ventilation due to the blockage. The workmen went home but forgot to remove the thing in the stack, the boiler started to catch fire as it continued to overheat. The dumb workmen killed a number of people in the laser tag game because some of the fumes got re directed through other ventilation shafts into their room. Most died of CO poisoning rather than the fire.
