Each of Bergman's films in this boxset are all masterpieces. If you are interested in exploring Bergman's films I strongly recommend this.

You get The Seventh Seal, Bergman's most famous film so a definite essential.

You get Persona, which is also considered as one of Bergman's best, it shows his more surreal side.

You get Wild Strawberries, which is Bergman's least depressing film.

And you get Autumn Sonata, which is a great introduction into Bergman's transition into colour.
