Winona Ryder

Winona Ryder says Mel Gibson made anti-semitic and homophobic remarks more than a decade before his infamous DUI arrest.

"Fifteen years ago, I was at one of those big Hollywood parties. And he was really drunk," Ryder tells the January issue of GQ. "I was with my friend, who's gay. [Gibson] made a really horrible gay joke."

After it came up that Ryder is Jewish, Gibson "said something about 'oven dodgers,' but I didn't get it," Ryder says.

"It was just this weird, weird moment," she continues. "I was like, 'He's anti-Semitic and he's homophobic.' No one believed me!"

Gibson, who made anti-Semitic remarks to an officer after a DUI arrest in 2006, is currently under investigation by the Los Angeles County Sheriff's Department on possible domestic violence charges involving ex-girlfriend Oksana Grigorieva. Over the summer, several tapes of derogatory and profanity-laced tirades, allegedly by Gibson against Grigorieva, were leaked online.
