Pedro Pascal has launched a new attack on JK Rowling - defending his description of her as a 'heinous loser' as he declared how 'bullies' made him feel 'f***ing sick'.

The Game Of Thrones and Gladiator II actor has doubled down on his criticisms of the Harry Potter author over her gender-critical opinions in a new interview.

Pascal, 50, whose sister Lux recently came out as a transgender woman, initially made the scathing 'heinous loser' remark in April on Instagram.

He was responding to activist Tariq Ra'ouf who was calling for a boycott of any future Harry Potter projects due to Rowling's outspoken stance on trans issues.

The British writer, 59, had celebrated a ruling by London's Supreme Court determining that, specifically within the terms of Britain's Equality act, 'woman' meant a biological female and not gender.
