In his first role as Mad Max, he calmly navigated postapocalyptic Australia, disposing of bad guys without breaking a sweat. As William Wallace, he inspired an army at Stirling Bridge with his bellowing battle cries. Now Mel Gibson's fiery outbursts have landed him in hot water. In two obscenity-saturated rants, posted in their entirety on radaronline.com, Gibson spews racial slurs and threatens grave harm to ex-girlfriend Oksana Grigorieva, but not before demanding a little action first. The latest Gibson meltdown comes nearly four years after he was arrested for DUI and reportedly made anti-Semitic remarks to the arresting officers. Gibson publicly apologized, both generally and to the Jewish community, for his 2006 behavior.
