The Modern Art sawing in half illusion that Stephen performed on Holly is a revised version of the one he performed on Rachel Stevens in season 1. In the original version, the box completely enclosed Rachel, with only her face, hands and feet visible through holes in the front. In the version used in this episode, the box was smaller, and Holly's head and arms projected out of it through holes in the top and sides.
The closing illusion, Neon Nightlife, originally belonged to Orson Welles.
The sawing in half using clear-sided boxes that Stephen Mulhern performed on Holly Willoughby in this episode is called Clearly Impossible.
Stephen and Holly's performance of this episode's closing illusion, Heads Off, is sometimes voted by other magicians as one of the most baffling version ever performed. It usually relies on the use of identical twins, but as Holly doesn't have a twin sister, even magicians familiar with the illusion have trouble explaining how it was done.
According to Holly, when she took off her wedding ring so that Stephen could use it in a trick, it was the first time she'd taken it off since her husband had placed it on her finger during their wedding ceremony.
This episode's closing illusion, Bikini Blocks, was actually a double version of an illusion called the Mis-made Girl.
