A new study takes a look beyond the box office to analyse the success of a film.

According to film researcher Dr. Livio Bioglio, his research team " developed an algorithm that uses references between movies as a measure for success, and which can also be used to evaluate the career of directors, actors and actresses, by considering their participation in top-scoring movies." The research team used the algorithm as well as data from IMDb to study movie's influence on the film industry.

From 'Citizen Kane' to 'Psycho', these are the movies that have shaped the history of cinema.

  1. The Wizard of Oz (1939)
  2. Star Wars (1977)
  3. Psycho (1960)
