Willy Wonka's father was put in the script for the film. In the book his father is assumed to be dead since he menyions he doesn't have any family to speak of. Also, the parental/family issues were invented for the movie as well.
Similarities to the Tim Burton/Johnny Depp version:
-They both use squirrels (not golden laying geese)
-Charlie's father works in a cap-screw factory
-Oompa Loompa songs use some of Dahl's original lyrics
-Loompaland, Prince Pondicherry, the Russian forged golden ticket, Arthur Slugworth, the cream vaults, hair toffee, the nutroom, Ficklegruber, Prodnose, and chocolate birds are all mentioned.
I suppose the squirrels and the Oompa Loompas were a huge factor for me. I love the mention of some more things that the first did not mention. Although, I know in 2005 we had a lot more technology for movies than we did in 1971 so things were not mentioned like the chocolate birds.
