Knightmare was technically complex, especially for a show that was originally devised in the 1980s.
The show was created using chromakey (blue screen) to create an authentic fantasy environment. Initially the illustrations were created by David Rowe and visual effects were added by the Travelling Matte Company.
As the show progressed, these effects became more complex. By the final series, contestants could use a 'reach' wand to interact with elements in the dungeon.
