Mel Gibson's troubling behaviour is once again making headlines.

In a June 21 interview with The Sunday Times, Winona Ryder spoke out against anti-Semitic and homophobic comments she alleges Gibson made to her and a friend at a party in the mid-1990s. 

At the party, Ryder said, "Mel Gibson was smoking a cigar, and we're all talking and he said to my friend, who's gay 'Oh wait, am I gonna get AIDS?'"

"And then something came up about Jews, and [Gibson] said 'You're not an oven dodger, are you?'" she recalled.

Ryder, 48, whose birth name is Winona Horowitz, has previously described her Jewish heritage. She also said that Gibson "tried" to apologize at a later time.

Winona Ryder spoke of Mel Gibson allegations in 2010

If Ryder's revelation about Gibson sounds familiar, she did first relate the story about his comments in a 2010 interview with GQ.

In 2010, she said: "I remember, like, fifteen years ago, I was at one of those big Hollywood parties. And [Gibson] was really drunk. I was with my friend, who's gay. He made a really horrible gay joke.

"And somehow it came up that I was Jewish. He said something about 'oven dodgers,' but I didn't get it. I'd never heard that before. It was just this weird, weird moment. I was like, 'He's anti-Semitic and he's homophobic.' No one believed me!"

Mel Gibson's rep denies Winona Ryder's allegations

Gibson's rep has now responded, denying the allegations in a statement provided to The Hollywood Reporter.

"This is 100% untrue. She lied about it over a decade ago, when she talked to the press, and she's lying about it now," the rep said.

"Also, she lied about him trying to apologize to her back then. He did reach out to her, many years ago, to confront her about her lies and she refused to address it with him."

This is far from the first time that Gibson has been at the centre of controversy for hateful behaviour. Dating back to the 1990s, he's faced accusations of anti-Semitism, racism, and homophobia — prejudices which he's sometimes even displayed in public and in recorded rants.

In the aftermath of the controversies, he transitioned from his one-time leading-man reputation to the role of film director.
