One of Harry Potter's best friends in the 2011 movie – and over the course of the whole series – is Ron Weasley (Rupert Grint), a Hogwarts student who plays on the Quidditch team and just manages to scrape by in his classes. Ron is the youngest boy in a family of seven and is a "pureblood," or a person whose ancestors were all witches or wizards.
Director Alfonso Cuarón, who directed the third film in the series, "Harry Potter and the Prisoner of Azkaban," remembered asking each of the three main actors (Grint, Daniel Radcliffe, who plays Harry, and Emma Watson, who plays Hermione), to write an essay about their characters. Grint didn't complete it, and when asked why, said that Ron wouldn't have written the essay because he doesn't like schoolwork.
