The number of Hollywood feuds is practically unfathomable, and it's not always easy to keep up with the latest beef. Though problems often arise between co-stars when the cameras turn off, disagreements have been known to happen between directors and actors. The tabloids had a field day with Julia Roberts and Kiefer Sutherland during their notorious relationship, a distraction that caused a lot of tension on Steven Spielberg's Hook set in 1991. Spielberg accused Roberts of poor behavior on-set, but it's almost hard to imagine when looking back at both of their careers because neither of them seems to have endured any further instances of that nature since.
