The guillotine illusion used at the end of the episode is known as the "French Guillotine", and is generally considered to be the most effective version of the illusion as, when the blade falls, the victim's head can be seen to fall into the basket below.
In an interview where she talked about working with Stephen Mulhern on the show, Holly Willoughby commented that when she first watched a playback of the guillotine illusion from this episode, even she didn't believe it when she saw the blade fall and her head tumble into the basket. She stated that "If I hadn't actually felt the blade go through my neck and seen the basket apparently rush up to meet me as my head dropped into it, even I'd never have believed that he really had chopped my head off. Seeing my own headless body laying there on the guillotine was one of the freakiest things ever!"
