Celine Dion will reveal her battle with Stiff-Person Syndrome in a new documentary to stream on Amazon Prime Video (Alice Chiche)Pop megastar Celine Dion, who is suffering from a rare neurological disorder, is hoping to raise awareness about her condition with a new documentary that will soon stream on Amazon Prime Video. "I Am: Celine Dion," a feature-length film from Amazon MGM Studios, will offer a "snapshot" of the singer's life and career as she battles Stiff-Person Syndrome (SPS), Amazon said Tuesday in a statement. The studio did not give a release date for the documentary, which will be available in more than 240 countries and territories. Those with Stiff-Person Syndrome experience stiff muscles in the torso, arms and legs, with noise or emotional distress known to trigger spasms. The Quebec-born star's "Courage World Tour" began in 2019, and Dion had completed 52 shows before the Covid-19 pandemic put the remainder on hold.
