Willy Wonka bars, which were axed in the UK two years ago following poor sales, will be re-introduced in three flavours: Whipple Scrumptious Fudgemallow Delight, Nutty Crunch Surprise and Triple Dazzle Caramel.
The ad campaign to support the relaunch is being handled by JWT.
The range, which will be featured in the movie, will include gift products such as a cane filled with sweets, based on a prop in the film.
The Warner Bros movie, which stars Johnny Depp as Willy Wonka, is tipped to be a big family hit this summer. Nestle has been heavily involved in its production, helping to create elements such as the chocolate river in Willy Wonka's factory.
The relaunch will be supported by a golden ticket promotion, based on the competition in the film that wins Charlie and the other children a trip to the chocolate factory.
Nestle already markets the Willy Wonka range in a number of international markets, including Canada and Australia.
Warner Bros has signed 'Charlie and the Chocolate Factory' merchandising deals with several firms, including Penguin Books and Funrise Toy Corp.
Funrise holds the global toy licence and will develop play sets, action figures and games, while Penguin will rejacket the original novel, written by Roald Dahl.
