Akira Kurosawa's film, Seven Samurai, is an epic three-and-a-half hour long black and white film set in 16th century Japan.

It was released in 1954 and was the most expensive Japanese film ever made at the time.

It is widely considered as one of the most influential films in world cinema.

The production had its ups and downs, going over schedule and budget.

Akira Kurosawa's son Hisao was a nine-year-old boy at the time it was made.

He talks to Jen Dale about how his father made the movie and its impact.
