The article presents the history and current activities of Cinecittà in Rome, one of the most important film companies in the world, also known as „Hollywood on the Tiber”. The author draws attention to the fact that the research up to date has focused mainly on Italian cinema, while Cinecittà appears as a supplement to the critical analysis of that cinematography. Starting from the history of the production company, what dates back to 30’s of the XX century, the author shows how the Roman film town has changed over the years and what its legal situation is like. The next chapter describes the current activities of Cinecittà, where runs a professional film and television studio, which produces films, series, commercials, music videos, commercial events; a museum (Cinecittà si mostra) and an important and internatrional cultural institution (Istituto Luce) with educational and promotional range. The considerations are complemented with examples of films produced in the company. Summing up, the author suggests that Cinecittà deserves a separate and insightful elaboration, which does not still exist in Polish language.
