Both have strong differences from the book. The second film kept the same name as the book, "Charlie and the Chocolate Factory" and included the father character that was cut from the first film.

They are both adapted from the Roald Dahl book, 'Charlie and the Chocolate Factory'.

Roald Dahl was involved in writing the screenplay for the 1971 film - Willy Wonka and the Chocolate Factory, but because he failed to meet certain deadlines, the screenplay was completed by David Seltzer. Dahl later said that he had been disappointed in the amount of emphasis put on the Willy Wonka character and disowned the film. We can't know what he would have made of the 2005 effort, - Charlie and the Chocolate Factory, because Dahl passed away in 1990.

He is the main character in the film.

There are two versions of this film. The endings are different, but in each Charlie ends up owning the chocolate factory and his impoverished family is redeemed.
