Most expensive film produced (inflation adjusted)

The most expensive movie made is Pirates of the Caribbean: At World's End (USA, 2007), which had an estimated production budget of $300 million (then £146 million). If the budgets of films are adjusted for inflation to 2014 dollars, Pirates of the Caribbean: At World's End remains the most expensive production of all time. Its $339-million adjusted budget narrowly beats Cleopatra (USA, 1963), starring Elizabeth Taylor and Richard Burton (both UK), which cost $44 million (then £16 million) in 1963 – the equivalent of $337 million in 2014.
