SJP did a terrible thing - I have proof
I came across an article about Ed Wood and there was a link to an interview with Dorothy Fuller, who was Ed's wife and sometime partner in crime. She spoke of how SJP treated her when they met.

I've never watched any of Ed Wood's movies but even if Dorothy Fuller was a bad actress, who is SJP to judge?! She is an actress herself, subject to the same criticisms as Dorothy Fuller once did. The least she could was show a little humility and let her acting be the proof. The fact that she could blatantly insult DF like that says a lot about her personality.
