Samuel "Sam" Beauregarde is the husband of Scarlett Beauregarde and father of the third ticket winner Violet Beauregarde. In the novel he and his wife accompanied Violet and in the 1971 version he is called Sam Beauregarde (played by Leonard Stone), but in the 2005 Charlie and the Chocolate Factory, his wife is with their daughter at the factory. He is described in the 1971 film as a well-known local politician, a civic leader, a philosopher, and is shown to be a used car salesman as well.
He is not overly villainous, as not many negative attributes stand out unlike the kids in the tour. When accompanying his daughter to the factory, he seems gracious at first, glad-handing Wonka and giving him his business card which Wonka, a businessman himself, accepts. Mr. Beauregard seems amazed by the inner workings of Wonka's factory, such as the chocolate-mixing waterfall. His sole poor quality is not backing up potential business partner Wonka when Willy Wonka orders Violet to surrender the gum, instead expressing pride that his daughter had the first three course chewing gum meal, and when Violet says she tastes baked potato, he comments "With sour cream?" and laughs. Only when the side effects occur does he express concern "Violet, you are turning violet!" He is last seen escorted to the Juicing Room by the Oompa-Loompas, and angrily shouts "I will get you for this Wonka if this is the last thing I ever do!" His revenge was never shown, but implied to be annoyance over vengenance as he more calmly states "I got a blueberry for a daughter!"
