Old Royal Naval College

Even if you've never set foot in Greenwich, you'll probably be familiar with the grand stone facade of its Old Royal Naval College. This 18th century building is a much-used movie location that pops up endlessly in period dramas and fantasy flicks, including Bridgerton, Pirates of the Caribbean, Batman, Star Wars and Indiana Jones. Now, it's having a bit of fun with its cinematic history by inviting members of the public to turn up in costumes from some of the famous films, in a mammoth Guiness World Record attempt to host the largest gathering of people dressed as TV and film characters. So if you're a closet cosplay fan, the leading light of Halloween fancy dress parties, or just an all-round silly billy who loves putting on a novelty outfit, this one's for you. No need to book: just turn up on the day at 2pm, and have a ball. There'll be giant photo props on hand including a Bridgerton throne, Cruella's car, and a Batmobile, plus film-themed refreshments. But beware, you can't just throw on a cape and rock up: officials will check you're wearing recognisable elements from specific movie characters before you can join in the fun.
