* Copacabana Palace (2014)

It will cost you around £500 to spend a night at the Copacabana Palace hotel in Rio de Janeiro, but thanks to this one-off documentary, you can have a look around for nothing. Famous guests have included Orson Welles, Charles and Diana, Robert De Niro and Madonna. The fortunes of the Copacabana have changed since the 1960s-80s, when Brazil was ruled by a military dictatorship. Now the country's economy is booming and the rich flock to the hotel, where they rub shoulders with celebrities, while many employees live in the poorest parts of the city and take home less than £300 per month.
