Accomplice: London
Audience members are never more than a perfunctory part of the show -- usually it's just everyone fake-laughing on cue, or the Jimmy Carr audience really laughing, at you. Now comes a theatre performance where the audience is the show: Accomplice: London
From a US-based bro-sis team who've taken their gig to LA, NY, and now our own misty shores, this "part game, part theatre, part tour" involves groups of ten solving a mystery set in The South Bank's backstreets & bars via clues and puzzles left/enacted by actors along the way -- "kinda like Michael Douglas' The Game", except not presuming you're such an ass, even Sean Penn seems reasonable by comparison.
A day or two before the show, each participant receives a mysterious frantic phonecall with the starting location, where the group is given the first in a series of cryptic clues via tape recorders, coded maps, ransom demands, even fake police (who actually outrank Community Support Officers)
Along the three-hour tour, the actors and secretly complicit merchants will keep you constantly on your toes, with food and booze thrown in at various points to keep your stomach engaged as well; groups are heavily encouraged to interact with the cast, whose improv ensures no two performances are ever the same (so...showflakes)
As "the fun is in the surprises", details are being kept under wraps, but previous plots've involved middle-manning an organized crime scheme, and a kidnapped Hollywood starlet -- who'll be so grateful for her rescue she might even have sex with you, only to laugh when you perform like a 26-year-old virgin
