Richard Dreyfuss isn't.
I read Jaws in high school. And I loved Richard Dreyfuss in the movie.
Harry Potter has distinctive green eyes in all of the HP books. Daniel Radcliffe has blue eyes. They did try to adjust this in the first film, but the green contacts hurt his eyes so in the movies his eyes were changed to blue.
They also tried to give Emma Watson Hermione's two front buck teeth in the first film, but she couldn't talk with the fake teeth so they dropped it.
The point is...sometimes you try to put those parts of the character into the movie, but the logistics don't allow it. I remember hearing the commentary track on X1, and they did mention that they tried adjust the height between Wolverine and the other characters, but it was a pain to do (because most of the main cast besides Hugh was quite tall) and it took up too much time on an already tight schedule, so they had to let it go.
