HBO Max is going to war in September. Well, not really, but two of its most high-profile debuts this month involve going to battle. The A24 movie Warfare features Charles Melton, Kit Connor and other up-and-comers as Navy SEALs stranded in combat somewhere in Iraq. In the original HBO series Task, Mark Ruffalo stars as an FBI agent hunting down a domestic terrorist in Philadelphia. HBO Max isn't all about intense violence this month.
