Julia Roberts is making a feature film about Batkid.

Submarine Entertainment announced Friday that the star had secured the rights to remake the new documentary “Batkid Begins: The Wish Heard Around The World” as a feature. Roberts will both produce and star in the film, with Dana Nachman, the documentary’s director, serving as one of its executive producers.

“Batkid Begins” tells the story of Miles Scott, a Batman-loving 5-year-old who, after being diagnosed with leukemia, lived as a real-life superhero for a day when the Make-A-Wish Foundation turned San Francisco into Gotham City in his honor. Thousands of residents came out to participate, and the story went viral through the use of social media.

“It’s thrilling to me that Ms. Roberts and her team watched our film and were so moved by it that they want to dedicate their time and creative capital to make sure the widest audience possible will know and love Miles’ story,” Nachman said in a press release about the deal.

“Batkid Begins: The Wish Heard Around The World” premiered Saturday at the Slamdance Film Festival in Park City, Utah.
