EDIT: This was all covered much earlier in the thread so consider this just another voice in the Greek chorus warning you.
Thanks everyone for responding and posting. I've been able to connect with a ton of people and get a lot of insight and feedback. Appreciate your replies and interest in the film. I've read all the replies and will continue to outreach to people as interesting things come up or I need any additional insight. Thanks again.
I'm sure you're inundated with information and responses, and I'm far from a scholar on DSP, but I wanted to throw in my two cents, as someone who has dealt with people like him in real life, and have a sense of what he's trying to get out of this documentary.
Phil is a liar. He is a pathological and consummate liar. He lies about everything. He lies about his gambling addiction, he lied to the bankruptcy court, he lies about how much money he has, and what he spends it on. He lies explicitly, and he lies by omission. He lies by carefully wording things, and he lies by spouting nonsense. He lies to his audience, and he lies to himself. He lies because he never wants to be seen as wrong about anything, and he lies to protect his ego. He lies at such a constant rate that you can randomly click on any Tevin re-stream, and Tevin will be pointing out DSP contradicting himself within two sentences. He lies so repeatedly that even things about his life that should be statements of fact are muddled in a half dozen stories he's told about them: how popular he was in the fighting game community, why he got fired from his helicopter job, why he got fired from Best Buy, why he lost his various partnerships with Machinima etc., why he lost his Twitch partnership, what kind of "bills" and "taxes" he's needed to pay for, when he got his fucking cat, how often he eats out, how much he drinks, whether his "king of hate" persona was genuine or an act.
He stays insulated inside his house, and exercises domineering control over his chat, because he wants only his version of events to be the prevailing one. Just like with the Side Scrollers interview, he'll engage with the outside world to get "the honest truth about himself" out, which means he wants to disseminate his lies to a wider audience.
If you want to do this right you need to keep one rule paramount which is that
Phil cannot be trusted. You should consider everything he tells you suspect until you get confirmation from another source, preferably several.
This is also my own personal armchair diagnosis, but I also believe him to be an overt narcissist, someone who has to protect himself against narcissistic injury by any means necessary. That includes the lying, of course, but it also includes how he can never be wrong, how his lack of skill in games is always the fault of the games, how he reacts with outright hostility to mild criticism from his chat, his focus on 'masculinity', his weird "kiss-the-ring" behavior where he demands sniveling apologies from anyone who gets on his bad side, and his complete binary treatment of people where he either tolerates you, or excises you from his life the moment he finds any reason to dislike you (see how quickly, and with *how much invective*, he turned on Side Scrollers after the interview).
So that's my personal warning on how you should treat him as a documentary subject.
