According to the documentary, the wife of “Superman” star Christopher Reeve shared life-saving words after a tragic accident

The story of the development of “Superman” star Christopher Reeve from screen hero to real hero is documented for viewers all over the world.

“Super/Man: The Christopher Reeve Story” premiered at the Sundance Film Festival in January and is now being released in theaters to a wider audience.

A new trailer for the film features snippets of his family, including his children Matthew, Alexandra and Will, his late wife Dana, who died of lung cancer in 2006, and famous friends such as Susan Sarandon and Glenn Close.

In 1995, Reeve fell from his horse during an equestrian competition and was paralyzed from the neck down.

In the trailer, Reeve is heard saying about the accident: “I've ruined my life and everyone else's. I won't be able to ski, sail or throw a ball to Will. I won't be able to sleep with Dana. Maybe we should let me go.”

His daughter Alexandra is moved to tears as she remembers Dana running into his hospital room and saying, “I love you, I love you.”

Reeves' voice-over continues: “And then she said the words that saved my life: 'You're still you. And I love you.'”

While adjusting to his new life, Reeve became heavily involved in disability rights and fundraising for spinal cord injury research, primarily through the Christopher and Dana Reeve Foundation. He also pushed for legislation to support stem cell research.

“I felt like I had to do something, not just for myself, but for everyone else who feels the same way,” says Reeve in the trailer for “Super/Man.”

Nine years after his injury, Reeve died in 2004 at the age of 52 from the effects of an infection and suffered a heart attack.

“And then she said the words that saved my life: 'You are still you. And I love you.'”

“With 2024 being the 20th anniversary of our father's death, we felt it was the right time to reintroduce him and his heroic story to the world,” his youngest son Will told Deadline in January.

Will thanked the team behind the documentary, including directors Ian Bonhôte and Peter Ettedgui, adding: “It all came together in a way where we knew as a family that we could be open, honest, vulnerable and hand it all over to them to see what they got back. And that trust was rewarded in a way that we are just so thrilled about and can't wait for the world to experience too.”
