Every time a novel has a film adaptation, the original plot suffers little changes that only the readers of the book can see and usually, makes them get quite disappointed. However, that was not the case of the Girl with a Pearl Earring adaptation, which was a very accurate adaptation of the novel that left satisfied most of the readers.
Despite of this, there are some little differences between the novel and the film that would be interesting to point out:
Firstly, in the novel when Griet is sexually attacked by van Ruijven, the one who stops him is Cornelia, Vermeer’s daughter, by asking them what they were doing. While in the film, the one who stops the incident is Catharina, by calling out for Griet.
Secondly, in the novel Griet decided to leave the Vermeer house by herself, after the painting is discovered by Catharina. In the film, Catharina orders Griet to leave the household.
Finally, in the novel it is abundantly clear that Griet has married Peter, and has had children with him. Nonetheless, in the film nothing is mentioned about Griet and Peter’s marriage, let alone children.
As a curiosity, just mention that the rags Griet receives the pearls in at the end of the film, are almost the same colors she describes the clouds are earlier in the film. She says they are yellow, blue and gray, and the rags are yellow, blue and white.
