Philip Seymour Hoffman is in no way a Delta ST. I can easily see Beta, and Ti-ESTp would be my main hypothesis. Every fucking role he's played is an aristocratic Beta Se/Ni douchbagery. Ti arrogance/sarcasm and Fe humor is quite prevalent in his movies and is even evident in his public statements/interviews. The way he seems a bit reserved and appearance-conscious in the interview Steve posted seems like typical Fe HA behavior to me.
