It was too painful a topic to discuss.

When asking about his immediate family in interviews, this permanent A list actor/writer/director/producer/auteur would mention that he had an older brother but didn’t give any details about his whereabouts. It was too painful a topic to discuss. His older brother was institutionalized as a child because he had "learning difficulties" (which is a long ago term for someone on the autism spectrum) and was prone to violent outbursts.
