Mel Gibson has said that renewed allegations of anti-Semitic comments levelled against him by actress Winona Ryder are "100% untrue".

The 64-year-old Braveheart actor has said a claim from the 48-year-old Stranger Things actress that he made antisemitic and homophobic remarks to her at a party is untrue.

In a statement provided to Variety, a representative for the Oscar-winner denied a story recently retold by Ryder in an interview.

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

"Also, she lied about him trying to apologise 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."

Ryder first accused Gibson in 2010

Ryder first accused Gibson of making the alleged comments in an interview with GQ magazine in 2010, suggesting he was referencing the gas chambers used by the Nazis during the Holocaust.

In 2006, Gibson was recorded delivering a controversial anti-Semitic rant after a drink-driving arrest.

He returned to directing for the first time in 10 years with 2016's Hacksaw Ridge, about the first conscientious objector to be awarded the US' Medal of Honor in the Second World War.
