Actress Fiona Shaw portrays Petunia in the films, with Ariella Paradise playing her as a child.Dudley Dursley is the only child of Vernon and Petunia, Marge's only nephew and Harry's only cousin.In the film version of Harry Potter and the Deathly Hallows – Part 1, she leaves Harry without showing any sentiment; however, in a deleted scene on the Blu-ray/DVD release, Petunia shows acknowledgment of the wizarding world, and ultimately deep sadness and remorse for the loss of her younger sister Lily, reminding Harry that she lost a sister as well.In Harry Potter and the Cursed Child, Petunia Dursley is mentioned as having died a few years after Harry's second son Albus Severus started studying at Hogwarts.They are all Muggles, and despise all things related to magic – and anything out of the ordinary in general – and the Wizarding World, especially the Potters.
The Dursleys live at Number 4, Privet Drive, Little Whinging in Surrey, England.
Vernon also has an aversion to imagination, to any references to magic, and anything even slightly out of the ordinary; in the first book, when Harry mentions dreaming about a flying motorbike, Vernon responds by angrily bellowing that motorbikes do not fly, despite Harry's protests that it was only a dream.
When the Dursleys decide to leave Privet Drive to go into hiding, Vernon nearly shakes Harry's hand good-bye, though he ultimately cannot bring himself to do it.
Described as a very large, blond boy (though dark-haired in the films), Dudley is generally given his way in almost everything, and shows the symptoms of a spoiled brat.
Dudley is a cold-hearted bully and the leader of a gang of thugs with whom he regularly beats up Harry and younger children on the flimsiest of excuses.
