In America, Saturday Night Live has been a television institution for the past 50 years - and now it's being given a makeover for its first foray over the Atlantic to the UK. Broadcast live each week, this brand-new UK version brings the high-wire, anything-can-happen energy that makes SNL a cultural force, now reimagined through a distinctly British lens. A new guest host will take the helm each week, putting their distinctive stamp on the SNL formula alongside a chart-topping musical guest. Alongside each celebrity guest host will be a chart-topping star who will perform throughout the night as well.
