" I … Do you understand how that feels like a dismissal? "
Hoffman replied:" It's hard to answer that question, you were not there … "
Hoffman also questioned whether Oliver believes that everything printed on what his accuser says happened.
"Do you believe in this that you read?" Hoffman asked.
"I believe what she wrote, yes," Oliver answered.
"Why?" Hoffman asked.
"Because it does not make sense to lie," Oliver said.
"Well, there is a point where I do not mention this for 40 years," Hoffman said.
"Oh, Dustin," Oliver said, as he put his head in his hand.
Hoffman went on to talk about the behavior in the movie sets along with some of the more colorful chats and jokes that would often take place between the film teams and the actors.
Hoffman described how his co-workers were "a family", who sometimes said stupid sexual things, that were meant to be fun. He reminded Oliver and the audience that this was 40 years ago.
Oliver said: "He does not feel self-reflective in the way that the incident seems to demand it.
