Fox's new reality show pilot called Smile, You're Under Arrest features people with outstanding warrants getting tricked for the audience's amusement before being arrested.
Fox President of Alternative Entertainment Mike Darnell calls it "a reverse Punk'd. Instead of the worst day of your life and then a joke at the end, this is the reverse. This is the best day of your life, and then we arrest you."
One of three set-ups just shot in Arizona features the cops luring a criminal to a movie set with the promise of making him an extra and paying him a couple hundred dollars. An elaborate film set is staged and filming begins on a faux movie. The set-up continues as the director then gets mad at the lead actor, fires him and replaces him with the law-breaking extra.
The scene escalates with the fake director introducing the mark to a supposed studio mogul and continuing to create this dream-comes-true sequence. Finally, all the participants are revealed as officers of the law, and the criminal is apprehended (before signing waivers to let the footage be used in the show).
UPDATE: Fox is working with the Maricopa County Sheriff's Office on this show, which is no surprise. Here are some previous posts about Sheriff Joe Arpaio and the Maricopa County Sheriff's Office:
