Derren Brown: Trick of the Mind

Derren visits the Valley of Fire, Nevada, where he makes the sun disappear and then shows viewers how he did it. He conducts the same experiment on a group of people in Hollywood, Barcelona and London, and Matt Lucas is dumbfounded by a card trick.

Derren uses his powers of misdirection and illusion to win a blindfolded noughts and crosses game in London, and finds water divining in the Nevada desert is thirsty work. A group of strangers invited onto the show find they all have something in common.

Derren travels to Vienna, where he performs a perplexing effect on the giant Ferris wheel featured in Orson Welles The Third Man. He also manipulates a cinema audience to forget a film they have just watched, while Stephen Merchant takes part in a game of fifty-fifty chance.
