Charlie and the chocolat factory-Differences in the movie and book

Charlie and the Chocolate Factory

In the movie i noticed that they told you more about the characters pasts. grandpa Joe had been working for willy Wonka, a more detailed version on how willy Wonka met the Oompa Loompas. , 
In the book, they didn’t mention Charlie’s parents very much.
In the book 2 tickets was found after 1 day, but in the movie, just 1 ticket were found each day.
In the book when Charlie found the money and went into the store, he first bought one and ate it, then bought one more and found the golden ticket but In the movie he found it on the first one he bought.
In the movie it was 10 pence that he found but in the book it was 50 pence.
When Charlie found the ticket in the movie he wanted to sell it because he’s family needed the money more than the chocolate, but in the book he didn’t say anything about selling it.
Charlie’s family’s house looks totally different in the movie and book, in the book the house looks just like a little shack, but in the movie it looked like a house that was totally wrecked and tilted.
In the book, everything is happening around 1940, but in the movie, it’s a mix of both new and old. For example, there is cars and TV games that looks to come from late 80’s or early 90’s but the stores and clothes on people looks to be from the 40’s. 

In the book, Willy Wonka stood waiting for the winners behind the big gate, but in the movie the winners walked past the gate and then watched a  singing puppet show with fireworks before Willy Wonka showed himself.
Willy Wonkas clothes was also more colorful in the movie than the book.
In the book the winners presented their self when they first saw Wonka outside the factory, but in the movie they did it inside the factory.
It’s many small differences in the movie and book that I haven’t mentioned, but I will end it here
