The Last of Us' star called out the 'Harry Potter' writer’s transphobia in an Instagram comment after Rowling celebrated a UK ruling, which found that transgender women should not be recognized as women.

Pedro Pascal has dubbed JK Rowling a “heinous loser” after the Harry Potter author celebrated the UK Supreme Court’s recent ruling that trans women are not legally women under the Equality Act.

Though actor Pedro Pascal, star of HBO’s “The Last of Us,” already has plenty of attention for his character’s dramatic season two arc, the upcoming star of Marvel’s “The Fantastic Four: First Steps” is raising eyebrows for comments he recently made about the creator of a different book and film series.
