James Franco has denied accusations of sexual misconduct, saying claims made by two women were "not accurate".
In an interview with late show host Stephen Colbert on Tuesday, Franco was asked about recent allegations of sexual assault and sexual misconduct.
On Sunday, as Franco picked up a Golden Globe for his performance as Tommy Wiseau in The Disaster Artist, actress Violet Paley accused him on Twitter of pushing her "head down in a car towards your exposed penis", and also trying to pick up her 17-year-old friend.
Seventeen is the legal consent age in New York, but it is unclear where the alleged encounter took place.
Paley has also said she has had a consensual relationship with Franco, but added that this encounter had been against her will.
At the same time, a former student of Franco's acting school posted on Twitter that the actor had paid her $100 to strip naked in a film scene, something for which she signed a "vague and general at best" contract for.
"Remember a few weeks ago when you told me the full nudity you had me do in two of your movies for $100/day wasn't exploitative because I signed a contract to do it? Times up on that!" she tweeted.
During the Globes' broadcast, actress Ally Sheedy tweeted her discomfort with Franco's win, but quickly deleted the tweets.
"James Franco just won. Please never ask me why I left the film/tv business," she wrote.
"Why is a man hosting? Why is James Franco allowed in? Said too much."
When asked about the accusations by Colbert, Franco said he had "no idea what I did to Ally Sheedy".
"I directed her in a play Off Broadway," he said. "I had nothing but a great time with her, a total respect for her. I have no idea why she was upset."
Franco went on to add: "The things that I've heard that were on Twitter are not accurate, but I completely support people coming out and being able to have a voice, because they didn't have a voice for so long.
"I don't want to shut them down in any way. I think it's a good thing and I support it."
He added: "The way I live my life, I can't live if there's restitution to be made. I will make it. So if I've done something wrong, I will fix it. I have to. I mean, I think that's how that works."
"I'm here to listen and learn and change my perspective where it's off, and I'm completely willing and want to."In 2014, Franco was accused of hitting on a 17-year-old fan, after she leaked private Instagram messages he had sent her after meeting her at a premiere.
"I guess I'm, you know, embarrassed, and I guess I'm just a model of how social media is tricky," he said at the time.
"In my position, not only do I have to go through the embarrassing rituals of meeting someone, but sometimes it gets published for the world."
