Mum of actress who engaged in real-life sex and ejaculation scene had concerned reaction to daughter's performance

The mum of an actress who engaged in a real life sex and ejaculation scene was left with concerns following her daughter's performance in the movie.

Margo Stilley - who originally didn't want her name in the credits - appeared in the flick alongside actor Kieran O'Brien.

The very erotic movie - which followed a series of intense sexual encounters between the pair - featured a completely unsimulated sex scene, where O'Brien's character, Matt, ejaculates.

'Unsimulated' sex scenes generally refer to scenes that are performed, rather than simulated.

The decision to have unsimulated sex scenes in the film - titled 9 Songs - proved to be a controversial one, with the movie infamously holding the title of the most sexually explicit mainstream film.

Aged just 21 at the time, Stilley had also been cautious about having her name attached to such a racy film, initially asking to be identified only as 'Lisa' (her character's name) instead.

Following the release of the movie, Stilley's mother, Debbie Collins, had concerns over the growing controversy.

She asked: "Did she use her real name?

"I pray for her every day, twice a day.

"Everything has to be done in a sexual way these days.

"And I know what they can do in Hollywood; how they can take someone's head and put it on another person's body.

"She had very deep faith in God."

Stilley spoke about her thoughts on having sex on camera, explaining that she is 'proud' of the movie.

Speaking to The Irish Examiner in 2008, she said: "You'd think I invented sex! I got told I was a whore and a sl*t and how could I do it.

"And what kind of role model did I think I was giving young women?"

She added: "It was a film about love and sex. It wasn't porn. I mean, I had sex with my boyfriend last night and that wasn't porn."

Meanwhile, Speaking to The Guardian back in 2005, O'Brien said: "It wasn't difficult for me to make and I'm really proud of it.

"Honestly, I don't know what all the fuss is about. It's a film about two people in a monogamous relationship, having sex as you'd kind of hope that everyone does.

"It's the age-old cliche: if you don't want to be offended, don't see it. But really I can't believe that people will be offended.

"I don't think anyone really was - they either didn't see it or they saw it and affected that reaction."

The movie, which was directed by Michael Winterbottom, was particularly criticised by Ann Widdecombe, who compared it to pornography.

At the time, she said: “It is not the [BBFC’s] role to allow pornography to enter the mainstream."

But the critics didn't fuss O'Brien, who only has fond memories of filming.

He added: "The film to shoot was bizarre and incredible. I doubt I'll experience anything like it.

"At some points, I would be taking direction from Michael standing naked with no mistaking where he could hang your towel, if you know what I mean.

"Michael would be wondering where to put his eyes. A lot of it was very funny."
