Mother of actress who shot ‘messy’ real sex scene shares her reaction to daughter's performance

The mom of an actress who engaged in a 'messy' real-life movie sex scene was left with concerns following her daughter's performance.

Margo Stilley - who has since featured in 2008's How to Lose Friends & Alienate People alongside Simon Pegg and Megan Fox - appeared in the erotic flick alongside actor Kieran O'Brien.

The 2004 flick followed a series of various intense sexual encounters between a British scientist (O'Brien) and an American exchange student Lisa (Stilley).

There is one scene where O'Brien's character literally ejaculates, with the decision by filmmakers to have unsimulated sex scenes in the movie proving divisive.

In fact, the movie, which is titled 9 Songs, infamously held the title of the most sexually explicit mainstream films.

Stilley didn't even want to be on the film's credits originally, initially asking to be identified only as 'Lisa' (her character's name) instead.

Following the release of 9 Songs, 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."

Amid all the criticism, Stilley defended the 2004 film in an interview with the Guardian that year.

She said: "It isn't shocking. If you know you are going to watch a film like this, it's not abrasive. It's normal sex that everyone has, not crazy stuff.

"I'm surprised [by the controversy], and even more by the fact that I've brought most of it on myself."

Unfortunately, the actress has revealed she endured a lot of abuse since 9 Songs released.

According to Stilley, she had people 'shouting abuse at her' at press conferences and calling her a 'wh**e' and a 's*ut' and asking her 'how could I do it'.

She told The Irish Examiner in 2008: "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."

9 Songs is 20 years old this year with many reminiscing on the raunchy flick.
