Derren Brown: Trick or Treat (2007-2008)

In the criminal justice system, the people are represented by two separate, yet equally important, groups: the police, who investigate crime; and the district attorneys, who prosecute the offenders. These are their stories.

When a secret prison suffers a mysterious explosion that allows the nation's most violent serial killers to escape, a former profiler is thrust back into a thrilling game of cat and mouse. Alongside a team of soldiers, spies and special agents, she has no choice but to track down and recapture these dangerous criminals… before they kill again.

The Irrational follows world-renowned professor of behavioral science Alec Mercer as he lends his unique expertise on an array of high-stakes cases involving governments, law enforcement and corporations. His insight and unconventional approach to understanding human behavior lead him and the team on a series of intense, unexpected journeys to solve illogical puzzles and perplexing mysteries.

Part guessing game and part singing show, The Masked Singer sees 12 famous faces compete to pull off the best performance, with their identity elaborately and imaginatively concealed, thanks to an expert team of talented costume designers. The stars will be transformed and they will take on a masked identity and become a fantastic character which will disguise them for the whole series. 

Forget any thoughts of fancy dress – they'll be full-on, original, movie-standard creations taking inspiration from worlds as varied as manga, superheroes, and wild animals and mythical creatures. Their transformations will be total, even their speaking voices will be disguised in interviews. 

It will be up to a superstar panel to lead the viewers at home in their quest to discover who they are. Although the stars aren't judged on their voices, they'll still need to give their best performance – the audience's least favourite will be eliminated, before the panel try to guess their identity and unmask them.
