In the past, they have had showings such as Top Gun, Bridesmaids, and Get them to the Greek. Movie-goers can purchase either an individual ticket or the whole tub! The showing for Top Gun took place at the old Stoneditch Underground Station, which I think would be an experience in itself. What a fantastic location! Sort of an underground-party-meets-summer-fun type venue. Maybe it's just me, but having the opportunity at night to be in a closed-down location that served so many travelers, once upon a time, piqued my interest.
They are currently based in London and "popping up" all around the UK, but they are planning on taking the experience international. On their website, they offered one in New York with the promise of more to come. In the summer, they hold their event outdoors, including taking over rooftops. In the autumn and winter, the events are held indoors.
