Vincent Crabbe, played by Jamie Waylett, was not in the last movie Harry Potter and the Deathly Hallows: Part II, because he was arrested for possession of Marijuana and a knife and was also accused of making a petrol bomb and taking part in the London Riots. He was arrested and served two years and was therefore unable to film his scenes for the movie. Louis Cordice, who played Blaise Zabini replaced most scenes as the third member of the Slytherin gang, and therefore, Crabbe was not in the movie at all.
