Gwyneth, who plays Phoebe in the movie, will let the audience see more than just her acting chops. And we mean that in the literal term as she was filmed wearing nothing more than a pair of black undies while performing a lap dance.

"Hey baby, you wanna dance?" she teases Mark's character, Adam, who is both an environmental consultant and a sex addict.

Phoebe, for her part is a cancer survivor and fitness fanatic rolled into one.

Like other couples, the two deals with their share of challenges. Things are just relatively more complex than usual since Adam is going through the process of recovery at the same time.

But besides the two, the lives of the other characters also reflect how the addiction affects the people around the victim and his or her relationships with them.

Although it tackles a serious issue, the creators managed to inject humour into it as it narrates the story of a group of people who struggles to resist the temptations of the flesh. They are also undergoing treatment for their addiction.

For instance, there's Dede, played by Pink who became part of the group since she has problems dealing with the opposite sex outside the context of an intimate encounter. There, she crossed paths with Josh Gad's character, Neil, who harasses women while riding a public transport system is similarly trying to correct his ways.

"Thanks for Sharing" is the directorial debut of Oscar nominated filmmaker Stuart Blumberg. He also co-wrote the script.

It is also the feature film debut of Pink, who is Alecia Moore in real life. The singer has already been commended for her onscreen performance. She "proves a capable actor and relaxed, enormously likable screen presence," said David Rooney of The Hollywood Reporter.

Tim Robbins, Josh Gad, Joely Richardson, Patrick Fugit and Carol Kane are also in the cast.

The film's showing is set on September 20. It already premiered at the Toronto International Film Festival during the weekend though, over a year ago.

"Thanks for Sharing"'s theme is not something new. There's "Shame" starring Michael Fassbender. "Choke", the film that premiered at the Sundance Festival in 2008 also focused on the same topic. Perhaps, one of the messages is that the problem brought about by sex addiction is all too real that we can't ignore it. It is a sensitive topic but a serious one, too. People close to us, or even ourselves, may just be struggling to combat it all these times.
