Why did Robert shaw and Richard dreyfuss not like each other?

Answer 1

It's a complicated story really.

The Robert you saw in Jaws is the Robert you would get in real life, that very wise, yet cocky and no nonsense attitude was how Robert was in real life, judging from interviews and what other actors have said about him. Because of this, he was the type of guy who would give you a hard time if you're not doing something right, and he had no problems telling you what he thinks or putting you in your place when you get out of line. He may have seen Dreyfuss has weak, since Dreyfuss is a bit of a nerdy guy. But, from what I've heard in interviews with the director and other actors is that Dreyfuss would constantly complain on set about being in the middle of the ocean, on a hot day, in a wet boat, and how he should've taken this role down and done another film and stuff like that, and that Shaw took an immediate disliking to him because of this, so that's probably where the tension comes from as well.
