How about...
Lord of the Rings
Harry Potter
Die Hard
Forrest Gump
Hunt for Red October
Jaws
The Princess Bride
Silence of the Lambs
Under Siege
You can add Fight Club to that list as well. As far as I remember the writer of the book thought the ending of the film was much better than the one in the book.
Anyway, I don't think they're more rushed than other movies.
