It follows the Oscars envelope fiasco which resulted in La La Land mistakenly named as the winner of the best picture gong instead of coming-of-age drama Moonlight.“We treated last night’s packed screening of Moonlight to a little extra something,” the cinema posted on Facebook. Rio Cinema manager Andrew Woodyatt told Metro.co.uk the audience got the joke and “everyone loved it”.“It would have been quite awkward if they hadn’t got the joke- but luckily they did,” he explained. Well done @riocinema for playing the beginning of La La Land before tonight’s showing of Moonlight.— Zef 🌵 (@ZefTillDeath) February 27, 2017 Just booked my ticket for Moonlight tonight @riocinema Hope they don’t show LaLa Land instead…(Bargain too, only £4 with Friends card)— Paul Treloar (@PaulieTandoori) February 27, 2017 Awkward: The Oscars mix-up Credit:AP “We played the beginning of one of the La La Land trailers, which is not exactly like the opening of the film, but everyone in the audience were [like], ‘hang on a minute, something’s wrong here’.“We stopped it, made it look as though we made a mistake, and then started Moonlight. It got a huge round of applause and everyone loved it.”’Envelopegate’ was the highest-profile fiasco in the ceremony’s history, with the Oscars launching a formal investigation and promising to take “appropriate action” following the mix-up. Apparently @riocinema played the first 20 seconds of La La Land before their showing of Moonlight yesterday. Complete genius.— Clement (@clem_murphy) February 28, 2017 A cinema in East London took inspiration from the Oscars mix-up by playing La La Land at a screening of Moonlight as a prank on the audience.The Rio Cinema, a Grade II listed Art Deco building in hipster hotspot Dalston, played 20 seconds of the Oscar-winning musical romcom starring Ryan Gosling and Emma Stone at the beginning of the screening. Props to @riocinema in #Dalston for playing the first 20 seconds of La La Land immediately before last night’s screening of Moonlight pic.twitter.com/2ZLllrnPFq— Sophie Dukebox (@sophiedukebox) February 28, 2017 Want the best of The Telegraph direct to your email and WhatsApp?
