Mind Mangler: A Night of Tragic Illusion is a new parody from the creators of  The Play That Goes Wrong—this time aimed at magicians. The production is about the relationship between a magician and his stooge, played by Henry Lewis and Jonathan Sayer respectively, who cowrote this show as well as Play That Goes Wrong with Henry Shields. While Mind Mangler easily segues back and forth from a spoof of a magic show to actual sleight of hand to a dramatic story involving the two leads, not all its parts are equally successful.
