From rooftops to hot tubs, there are now loads of places around London where you can watch a movie without having to step foot in cinema, but Secret Adventures have taken it to a whole new level (literally) with their Adventure Films Underground. Their screenings of award-winning adventure films take place in the Brunel Museum Shaft under the Thames. And you can forget stale popcorn as well; snacks and drinks here include street food, wild cocktails and honey beer, which can all be enjoyed around a campfire at the Brunel Roof Garden before and between the films.
