Movies where co-stars visibly hate each other?

I was reading about the troubled production of The Last Boy Scout, the 1991 Bruce Willis/Damon Wayans buddy action-comedy. Apparently Willis and Wayans absolutely hated each other, but their on-screen chemistry is still pretty good.

So I got to thinking about movies where the opposite is true; movies where the performers' contempt for one another is clear in the picture.

Do you have one in mind?
