Former child star Macaulay Culkin has opened up about the shocking abuse which led him to leave Hollywood.

Culkin, 37, claimed his father, Kit, was "mentally and physically" abusive and "jealous" of him, and made threats including, "Do good or I'll hit you".

The reclusive actor made the claims in a revealing interview with Marc Maron on his WTF podcast.

The Home Alone star took his parents to court when he was 15-years-old, over his US$17 million earnings.

"Everything he (Culkin's father) tried to do in life, I excelled at before I was 10-years-old," Culkin told Maron's WTF podcast.

Culkin's parents divorced after he filmed Richie Rich in 1994, which he called "one of the best things that's every happened" because it led to him leaving Hollywood.

"I even wanted to take a break for a while and eventually I was like 'I'm done guys, hope you all made your money because there is no more coming from me,'" he said.

Meantime, Culkin — who, as a child, was close friends with Michael Jackson — also spoke about his relationship with Jackson's daughter, Paris Jackson, 19 (Culkin is her godfather).

"I am close with Paris," Culkin told WTF, according to E!.

"I'm going to warn you now I am very protective of her so just look out. I am a very open book when it comes to things but like with her, she is beloved by me."
