Rusty Dennis was not the kind of mother Hollywood usually puts on screen. She rode with motorcycle gangs, partied hard, and told people the rest of the world was nuts. But when doctors told her that her four-year-old son Rocky would be blind, intellectually disabled, and dead before his seventh birthday, she refused to accept any of it. She spent nearly a year bringing him to UCLA Medical Center multiple times a week until the diagnosis finally came down: craniodiaphyseal dysplasia, a disease so rare that in 1965 only six other cases had ever been recorded in medical history.
The condition causes abnormal calcium deposits to accumulate in the skull, thickening and pushing outward, distorting the face, compressing the brain, and slowly destroying vision, hearing, and neurological function. The doctors gave her a death sentence. Rusty essentially told them she would see about that. Rocky Dennis was born Roy Lee Dennis on December 4, 1961, in Glendora, California, to Florence Rusty Tullis and her second husband, Roy Dennis.
He got the nickname Rocky as a baby because he would not sleep unless someone rocked him. As a young child he suffered frequent ear and sinus infections, nothing out of the ordinary. Then, around age two, he went in for a tonsillectomy, and the X-ray technician noticed something wrong with his skull. That discovery set off the long procession of medical visits that led to the diagnosis.
Rather than institutionalize her son, Rusty pushed schools and doctors to treat Rocky like any other kid. When doctors claimed his eyesight was too poor for reading, she dismissed it. When schools tried to move him out of mainstream classes, she fought back. She believed the resistance came not from Rocky’s intelligence, which she insisted was intact, but from other parents’ discomfort.
Rocky proved her right. He graduated from Sandberg Junior High as an honor student after starting academically behind. He was elected best buddy, most good-natured, and friendliest camper. He tutored classmates for three dollars an hour and negotiated the rate himself.
He memorized the night sky. He fell in love at summer camp with a blind girl who could not see his face but saw everything else. When doctors offered surgery to correct his features, he asked, Who will I see in the mirror if I change my face? He chose to keep his face.
Rusty herself had lived a life far outside any conventional mold. Born in Brooklyn on May 29, 1936, she was a Jewish truck driver’s daughter with a sharp tongue. At thirteen she was kicked out of junior high for truancy. At fourteen she was using cannabis and running with motorcycle gangs.
At fifteen she dropped out of school entirely and worked as a hoochie coochie dancer at Coney Island. She married her first husband, truck driver Tommy Mason, at seventeen, and their son Joshua was born a year or two later. That marriage fell apart, and she moved back in with her parents before marrying Roy Dennis and relocating to California. In 1961, Rocky was born.
By the time of Rocky’s diagnosis, Rusty had built her entire philosophy around a single conviction: if a person can make themselves sick, they can also make themselves well. She raised Rocky on that idea. Every time he had a headache or the pain flared, she sent him to his room and told him to make himself well. Rocky’s spirit suggests the approach gave him something powerful, a refusal to see himself as a victim.
But it was also a philosophy with a shadow, one that would matter enormously on the last night of his life. Rusty was a full member of the Turks, a motorcycle gang of rough, hard-living people who built their world around loyalty and blunt love. They adored Rocky. Her partner, Bernie Tullis, was the real-life basis for the character Gar, played by Sam Elliott in the film.
The biker circle surrounding Rocky was not set dressing; they were his family. And Rusty was direct about her substance use in a way the movie never captured. The film suggested she used because she was overwhelmed and drowning. Rusty rejected that framing.
She said she partied all the time and substances were part of the partying lifestyle. She was not a woman in pain reaching for a crutch. She was a woman who partied hard and owned it. By September 1978, Rocky’s health had declined sharply.
He was sixteen years old, and the disease that should have killed him before age seven had finally begun to win. He was in a wheelchair in his final weeks. The headaches that had been his constant companion his entire life had escalated to a level nothing could touch. On October 3, 1978, the family went out to a restaurant for dinner, and everyone could see how weak he had become.
That evening Rocky came home with a headache. Rusty did what she had always done. She sent him to his room and told him to make himself well. He never woke up.
Rocky Dennis died the following morning, October 4, 1978, at home in his sleep. He was sixteen years old, nearly seventeen. He had outlived his death sentence by nearly a decade. The movie Mask, released in 1985, shows Rusty discovering his body herself in a raw and devastating scene.
In reality, she was not at home when Rocky died. She was at her lawyer’s office dealing with a substance possession charge. Her partner Bernie called to tell her. The gap between the film and reality did not make Rusty a bad mother, but it revealed how much Hollywood smoothed the edges of an already jagged story.
By 1985, Mask was in theaters across America, directed by Peter Bogdanovich and starring Cher as Rusty and Eric Stoltz as Rocky. It grossed over forty-eight million dollars at the box office. Rusty Dennis had been paid fifteen thousand dollars for the film rights, and according to multiple interviews, most of that money went directly to pay medical bills for her older son Joshua, who was at that time undergoing treatment for AIDS. She did not sell Rocky’s story for profit.
She sold it to try to keep another son alive. When reporters descended on Rusty after the film came out, expecting gratitude and tears, they got something far more interesting. She called the film a fairy tale, not a tribute, not a beautiful memorial. For a 1986 Chicago Tribune profile, she said she had always thought showing Rocky’s courage would help disabled kids and their parents, who she believed were sometimes more disabled than their kids.
She did not realize the movie would be about her too. She praised Cher’s performance generously, telling the same reporter that Cher depicted the way she was very well, adding, I always thought I was perfectly normal. That the rest of the world is nuts. She also pointed out the two biggest factual departures from reality.
The film compressed more than a decade of events into what looked like about a year. And Joshua, her older son, was written out of the story entirely. That omission reportedly bothered her. Then there was the music.
Rocky Dennis had been a devoted Bruce Springsteen fan. Bogdanovich built the original soundtrack around Springsteen’s songs, but Universal Pictures could not reach a deal with Columbia Records and quietly swapped in Bob Seger tracks without telling the director. Rusty was not pleased. On a 1985 San Francisco talk show, she said flatly, I don’t think Rocky even knew who Bob Seger was.
Bogdanovich was so enraged he sued Universal for nineteen million dollars, claiming the music swap violated his final cut privilege. The Springsteen songs were restored for the 2004 director’s cut DVD, twenty years after Rocky’s story first reached theaters. Joshua Mason was the son Hollywood erased. In 1985 he was a writer in San Francisco.
A year later he was diagnosed with Kaposi’s sarcoma, the cancer widely associated with AIDS during the mid-1980s crisis. He was openly gay and described his mother as supportive, though she hoped for grandchildren and once suggested a sperm bank. Joshua died in 1987 at thirty-two. Rusty had now lost both sons.
She had sold one son’s story to try to save the other. In a Chicago Tribune interview she once said, Joshua doesn’t believe in dying, and neither do I. After Rocky died, Rusty moved to San Francisco and took up Buddhism. She worked as a counselor helping people facing challenges with substance use.
At the time of the film’s release she had plans to work at the Shanti Project, a workshop for the terminally ill, including AIDS patients. She still rode motorcycles. On October 14, 2006, Rusty, then going by Florence Tullis, was riding her three-wheel motorcycle when the right tire fell off. She lost control.
The bike struck a curb, and her body slammed into a telephone pole. She broke both legs and suffered a punctured lung. Friends and family had no idea what happened until a brief item in the San Gabriel Valley Tribune mentioned an unidentified seventy-year-old woman injured in a motorcycle accident. They connected the dots and went to her.
She survived the initial accident. The resulting infection was what could not be fought off. Florence Rusty Tullis died on November 11, 2006, at Beverly Hospital in Montebello, California. She was seventy years old.
Before she died, she never stopped being who she had always been. She said Rocky’s death was just another place to go, and he loved going places. She said death was something she and Joshua simply did not believe in. She never asked why me, not once, not for Rocky, not for Joshua, not for herself.
The screenwriter Anna Hamilton Phelan, who wrote Mask, put it simply: Rusty was not the PTA mother of the year, but she was the perfect mother for Rocky. The record confirms that Rusty never backed away from her philosophy, never apologized for it, and believed to the end that it had given Rocky something invaluable, the refusal to see himself as dying. Rocky Dennis died at home in his sleep, without machines, without a hospital, without indignity.
His mother had promised him that, and she kept that promise.
