Sera Johnston told BuzzFeed News she was sexually assaulted by the Ordinary People star in Vancouver in 1983. Hutton has strongly denied the allegations.
Johnston, now 50, says that the alleged attack took place after she and two friends were invited to his hotel room, reports The Sun.
Hutton, who won the Best Supporting Actor Oscar for Ordinary People in 1981, was in town filming the movie Iceman.
“It was like we were entertaining them – cute,” Ms Johnston told BuzzFeed News.
“We were funny, you know what I mean.”
She claimed Hutton sat down next to her and “was getting very close to me, you know, really kind of sidling up to me, and petting my legs and stuff.
“I was just, like: I think this is going to be bad. I was really wrong about this,” she told BuzzFeed.
Johnston said she told them “I don’t think this is a good idea” and “I don’t think my mother would be too happy about this.
“To everything I would say, it was, ‘It’ll be OK, it’ll be OK. It won’t last long and you’ll be fine.’”
She claimed to BuzzFeed that Hutton was soon kissing her neck, and he would take off her clothes despite her pleas.
Johnston said the actor, who was about 24 at the time, told her that she would like it and that his pal would watch.
“It hurt like hell,” she told BuzzFeed.
“I mean, it was very painful. God. Yeah, it was extremely painful.
“Horrible, horrible, absolutely horrible.”
She said the “MeToo” movement inspired her to come forward with her allegations.
Hutton – who saw his TV show Almost Family cancelled after one season on Monday – has denied the allegations.
The show based on the Australian drama series called Sisters, which starred Magda Szubanski and Barry Otto.
Hutton said in a statement to entertainment news website Deadline that he has been the “target of multiple extortion attempts” by Johnston.
“She threatened that if I did not meet her demands, she would go to the press with a false allegation that I sexually assaulted her 37 years ago in Canada.”
Hutton added that BuzzFeed “chose to publish Ms. Johnston’s false story.”
“BuzzFeed knew the truth because they were provided with documented evidence.”
The actor added that “I will not stop fighting to expose this story for what it is – a failed extortion attempt based on something that never happened.”
