Alice: Movie vs Book

I found that in the clip that we watched in class to be very different then what the book portrays.  During the tea party in the book, the Mad Hatter and other characters at the table have no idea who Alice is and they really do not want anything to do with her by telling her that there is no room for her.  In the short clip we watched, the Mad hatter quickly recognized Alice and invited her right over.  The movie strays away from the book in those little ways that make you think that there will be lots of those differences.
