Researchers in Italy have declared the Wizard of Oz the most influential film ever made, outstripping others in how much it has inspired and been referenced in the film industry.
The team awarded points to individuals depending on how influential a movie they were involved with was compared with other films released in the same year.
The team did not consider short films, adult films and those with no link or reference to other movies.
The team devised a separate approach for ranking actors and directors in order to get around the bias towards older movies.
