Dublado e Legendado no OverFlix. A fantasy depicting Madrid in the distant future when the city has become a port thanks to the transformation of the Manzanares River into a Suez-type canal affording passage to the grandest of ocean liners. There are some spectacular scenes as ship glide through the city and past the Royal Palace, a sight that strucks contemporary observers as fantastic. As of 2007, no copies appear to have survived.
