Since being diagnosed with a rare disorder and largely retreating from public life, many fans of Céline Dion have feared this may be the end of the road.

But the beloved singer seems determined to dispel rumours of her being stuck incapacitated at home and an upcoming Amazon Prime Video documentary promises to give new insights in the Canadian singer’s life.

The first trailer for I Am Céline Dion was released last week, with the documentary set for a June 25 debut on Prime Video.

Featuring a mix of old and new footage, the project promises to be an emotional watch for fans, many of whom took to social media to declare the sneak peek alone had tears falling.

“Céline Dion made me cry and her documentary isn’t even out yet,” one fan posted to X, formerly Twitter.

Just the trailer alone, I’m already in tears! I know when it finally premieres, I’ll need me a bucket

“This is just the trailer, but I’m already crying like a baby,” a YouTube user wrote.

The I Am Céline Dion trailer shows the singer talking about her passion for singing while the audience is treated to footage of her on stage, in recording booths, going through what appears to a storage unit full of personal belongings, and playing with her children.

She also delves into the impact of stiff person syndrome, a diagnosis that she revealed in 2022 and which led her to cancel a world tour in 2023.

The progressive autoimmune and neurological disorder can cause muscle rigidity and spasms.

There is no known cure, and Dion previously revealed the spasms affected every part of her daily life, including her ability to sing.

In an interview with Vogue released on Thursday, Dion recalled first feeling the symptoms of stiff person syndrome in 2008.

“Quite rapidly, I was having difficulty controlling my voice,” she said.

“It would go really high, and then it would spasm.”

In the documentary trailer, an emotional Dion said she was “working hard every day”, but it has been a “struggle”.

“I miss it so much. The people, I miss them,” she said.

“If I can’t run, I’ll walk. If I can’t walk, I’ll crawl.”

She told Vogue that physical, vocal, emotional and spiritual rehabilitation was needed.

“I wanted to do it as a documentary because it’s not a quick thing and there is no quick fix to what I’ve gone through,” she said.

“And I want this story to be told in a classy way. I respect my fans and myself enough for them to know the full truth.

“I hope that the documentary doesn’t frighten people but awakens people to SPS. It took 17 years for me – please don’t wait that long.”

The documentary appears to be a large-scale return to public life for the singer, who this year graced the cover of Vogue France and made a surprise appearance on stage at the Grammys.
