I remember reading an interview with River and he basically said "I just try not to think about that stuff"
The parents were never very.....Responsible sounding, to say the least, with their kids actually pulling in most of the income from a young age via musical or acting talent. They would also invite a bunch of random unfortunates to live at their place despite not exactly having the money to support them all. That and that fucking cult no doubt screwed up the minds of their kids something awful. The Children of God were basically an orgy.
Joaquim has been described as "a real nice guy, just too mentally fucked up to function most of the time".
Also River Pheonix hands down my favorite actor, just really hits me some kinda way the messed up stuff he had to experience.
