While 1999’s Three Kings became a very good film, the production was fraught with problems, notably with George Clooney and writer/director David O. Russell feuding throughout the extensive, delayed production.
Russell is known to occasionally have very contentious, embittered arguments with his talented actors, but this difficult working relationship with Clooney became one of his most public battles.
Actors and directors can often share beautiful, meaningful collaborations together, resulting in a healthy, progressive work environment where both artists express themselves fully, producing their best work.
