Before Beyoncé, there was Donna Summer, an innocent church girl who catapulted to fame as music’s bad girl and "Queen of Disco" during the hedonistic ‘70s era.
But the pop star struggled behind closed doors — and at one point contemplated taking her own life.
"In order to understand the greatness and magnitude of her triumphs, you also have to know the lows," the late star’s daughter, Brooklyn Sudano, told Fox News Digital. "You also have to know what we had to work through and overcome in order to get there and why she decided to do certain things."
Summer passed away in 2012 at age 63 from lung cancer. It was a shock to both fans and many friends as the singer kept her diagnosis a secret, only telling her husband and children. She is now the subject of a new documentary premiering Saturday on HBO and HBO Max titled "Love to Love You, Donna Summer."
The film, co-directed by Sudano and Oscar winner Roger Ross Williams, features never-before-seen home videos. It also highlights rare sit-downs with many of those who knew and loved the private icon.
Summer, born LaDonna Adrian Gaines in Boston, was one of seven children who began singing in the church choir. In the ‘60s, she joined the Munich company of the rock musical "Hair" and headed to Germany. In 1972, she married Austrian actor Helmuth Sommer, a union that lasted until 1976. Two years before the couple called it quits, Summer released her debut album "Lady of the Night" in Europe. But it was 1975 when the track "Love to Love You Baby" skyrocketed her to fame. She kept her ex-husband's name, slightly changing it her way.
Summer recorded the breathy, lovemaking anthem while lying on her back on the studio floor with the lights out, The New York Times reported. According to the outlet, she imagined Marilyn Monroe cooing the lyrics. The 17-minute single contained more than 20 simulated orgasms. She soon released two albums, "A Love Trilogy" and "Four Seasons of Love." With songs like "I Feel Love," "Hot Stuff" and "Bad Girl," Summer was promoted as a sex goddess.
"I think in order to portray something like that and own it in the way that she did, it has to be a part of you," Sudano explained. "So I don’t think that part of it was fake. It was just one part of her, one facet of her ability and charm. I think the struggle was that she was then put in a box as a performer… I don’t think she realized how big [things would get], but she understood that there was a door there."
As Summer’s highly erotic tune was played in nightclubs, she often thought of her religious upbringing. According to reports, her father once smacked her for wearing red nail polish because "that’s what whores wore."
In the film, Summer is heard saying, "You’re looking at me, but what you see is not what I am. How many roles do I have to play in my own life?"
Privately, Summer was carrying with her the pain of having been sexually abused by her pastor as a child. As her fame grew, so did her depression. In 1976, Summer nearly jumped out of a window of her New York hotel room. Her foot became entangled with a window curtain. As she approached the ledge, a maid walked in.
"Another 10 seconds, and I would have been gone," Summer later admitted. "I felt God could never forgive me because I had failed him. I was decadent, I was stupid, I was a fool. I just decided that my life had no meaning."
Sudano said it was important to address her mother’s trauma in the film in the hope it will encourage others struggling to speak out.
"It was multiple years with the pastor," she said. "This was stuff I had heard about as I got older about my mother. As we said in the film, there were a lot of secrets. There were a lot of things we didn’t talk about. But you’re dealing with the trauma, whether you know what the trauma is or not. And so, it was really important to flesh that out, for the audience to understand what she was carrying and had to overcome… I thought it was very important to tackle those things and show our family working through some of those things… If we can talk about it, maybe that will permit somebody else to talk about it as well."
"The experience has been very healing for us," Sudano continued. "It’s important to talk about these difficult things, things that may not be so easy to face. You’re never going to heal if it’s kept quiet or swept under the rug. Hopefully, this film will inspire other families to have those kinds of discussions."
Summer also endured an abusive relationship with artist Peter Mühldorfer, which is explored in the film. One beating resulted in Summer being left unconscious with a black eye and broken ribs.
Sudano and Williams tracked down Mühldorfer, who spoke out in the film.
"I hit her, and I never could forgive myself," he is heard saying.
Williams told Fox News Digital that he was shocked Mühldorfer was willing to participate in the documentary.
"I was really surprised," said Williams. "It took a while to get him to agree to do the interview, and it took a while to find him. But I think he really wanted to get this off his chest. And I think Brooklyn gave him the permission to do that because she’s Donna’s daughter. And it was a pretty amazing interview. It was pretty revealing. I’m sure it was quite emotional for Brooklyn. Even for me."
"I had spoken to my aunts and I knew that my mother had forgiven him," Sudano chimed. "So there was a certain permission that I felt in talking to him and having that part of this story in a real way. My mother… was somebody of great forgiveness. Even when people didn’t deserve it, she was very generous in spirit. And I think that through forgiveness, there’s healing. And through some of these hard conversations, there’s healing."
When the decadent ‘80s era rolled in, Summer focused on family. She married Bruce Sudano in 1980 and welcomed two daughters. She was already a mom to one daughter from her previous marriage. Summer also became a born-again Christian.
Despite her ongoing popularity, Summer became the subject of scandal when she was quoted as describing AIDS as punishment for homosexuality. Many of her LGBTQ+ followers boycotted her music as Summer repeatedly, and at times tearfully, denied making the statement. She later reconciled with gay organizations, The New York Times reported.
"The gay comments were a misconception," said Williams. "Donna had a lot of gay friends. I remember interviewing one of her close friends whom she knew from back from her days on ‘Hair.’ I remember him saying that she had gone through her religious reawakening, but she also took him out to gay bars… Donna loved everyone... I think people see this glamazon, but… she’s not at all what you think."
Over the subsequent years, Summer continued to record and perform. She and her family moved to Nashville and also kept a home in Florida.
"We had a really normal, but abnormal childhood," Sudano chuckled. "We would go on set, and then we would go to Sophia Loren’s house for dinner. It was definitely not normal, but our experience was also very grounded… Whenever we would go out, people would come up to her and thank her for her music or share stories of their lives with her."
Summer’s last dance, as it were, was 2010’s "To Paris with Love," her final single.
"I was a huge Donna Summer fan, [but] I only knew her as the 'Queen of Disco,'" said Williams. "What surprised me the most was that she was so much more than that… She was this complex artist and disco put her in a bit of a box. She continuously broke out of that box. She doesn’t necessarily get the credit that she deserves. It was like discovering a whole new artist that I thought I knew."
