A lot different to the movies, for a start it takes place at the end of the 19th century at the height of Britains Empirical Domination and yet shows (As has proved to be) that such Empirical Aspirations were merely a self deception.
Read the book and then judge the movies, you will find that the movies like so many other times are not a patch on the book and very much has been sacrificed from the story in the drive for popularism.
Also remember that this was written in 1898, in 1898 men had not even flown in an heavier than air machine yet (If you discount the contributions of Sir George Cayley in 1853), cars were few and far between, there were no such things as lasers, radio was pretty much in its infancy, only the richest people had telephones and a "computer" was a clerk in an office charged with the performing of mathematical aspects of accountancy.
This was far reaching for its time, something that modernisations through movie rewrites ignores. By all means watch the movies and then read the book and see precisely how shallow and pale the movies are in comparrison.
