Tim Roth reveals his grandfather sexually abused him and his father

Tim Roth revealed in a new interview that he and his father were both sexually abused by his grandfather as children.

In an interview with The Guardian, Roth spoke about his father's decision to leave Britain's communist party in the 1970s after a wave of sex scandals broke.

"He was an abused kid, my dad, and it was a terrible childhood that he had, and he took that s--t seriously," Roth said.

He continued, "[My father] was a damaged soul. I loved him. He was funnier than f--k. He was abused. And I was abused. But I was not abused by him. I was abused by his abuser.”

The "Lie to Me" actor said that his paternal grandfather abused his father as a child, and then later abused Roth as a child.

"Yeah. It was his father. He was a f--king rapist. But nobody had the language. Nobody knew what to do," he said.

It was that experience that inspired Roth's 1999 film "The War Zone." The film was based on the Alexander Stuart novel about a father abusing his daughter.

At the time, Roth spoke about how the story spoke to him as an abuse survivor.
