Emilio Estevez and Martin Sheen may work well together on screen, but they've had their share of issues in real life (via LA Times). The pair documented their relationship in their joint memoir, Along the Way: The Journey of a Father and Son. In the book, they touch on a difficult subject from their past. Estevez says that when he was 14 years old he was in the Philippines with his father, where Sheen was filming the movie Apocalypse Now.

Estevez recalls the vibe on set being dark and dangerous for a child, with alcohol and drugs flowing freely. He wanted to return to California and go back to school, which caused an argument with Sheen, who was a heavy drinker at the time. The father and son's conversation ended in a physical brawl, which was broken up by actor Marlon Brando. "I was trying not to hurt Emilio and trying to make sure he didn't hurt himself. Thank God Marlon arrived when he did," Sheen recalled (via Irish Examiner).
