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.
The illusion where Stephen Mulhern saws Mischa Barton into three and removes her middle section is called the "Sawing in Thirds" or "Center Cut" illusion.
The trick where Mischa Barton threaded a length of dental floss through the hole in her pierced ear, tied it in a knot and then pulled it out without ripping her earlobe was originally performed by Jane Curtin on a 1990 Penn & Teller TV special. In order to perform the trick, Mischa had to have her ears pierced especially a few weeks beforehand. Having kept them pierced for the photoshoot for her 2005/6 Accessorize advertising campaign, she then let them heal up again, and didn't get them re-pierced until 2009.
This episode's closing illusion, Modern Art, was invented by Jim Steinmeyer, and is a standing version of Sawing a Woman in Half.
This show's closing illusion, The World's Largest Card Trick, was devised and first performed by magician Mark Wilson, and is basically a sawing in four using giant playing cards to divide the lady being sawed (in this case Caprice).
This show's closing illusion, the Zig-Zag Girl, was invented by magician Robert Harbin in the 1960s. In the illusion, a lady (in this case Stephen's guest Jennifer Ellison) enters a tall vertical cabinet, and places her face, hands and foot through four holes in the front. Two blades are inserted through the cabinet, dividing it into three pieces, and the centre section is then slid to one side.
