As a classic Book Week character, the wacky and eccentric Willy Wonka always steals the show. He's from the beloved novel "Charlie and the Chocolate Factory" by Roald Dahl (1964) and brought to life by the one and only Gene Wilder in the 1971 film "Willy Wonka & the Chocolate Factory". With his fancy top hat, purple suit, and cane, Mr. Wonka is the epitome of "pure imagination" and a favorite for teachers to dress up as during Book Week.
