Back in 2013, our collective hearts melted as five year-old Miles Scott was granted his ultimate wish through the Make-a-Wish foundation: to become Batman for a single day. With the help of the city of San Francisco, thousands of volunteers, and President Barack Obama, Scott became the caped crusader and successfully defended the citizens of San Francisco. Miles Scott’s story is the focus of a new documentary premiering this week at Sundance-adjacent film festival Slamdance, but it won’t be the only time his story is told on the big screen—Julia Roberts is also making a movie about our beloved Batkid.

Deadline reports that Roberts will produce and star in a feature film adaptation of the new documentary ‘Batkid Begins,’ which tells the story of Scott, a five year-old leukemia patient who became Batman for a day. San Francisco was transformed into Gotham city, and Scott zipped around in a Batmobile to complete staged missions, which fans around the globe could track online. At the end of the day, Scott was granted the key to the city from San Francisco Mayor Ed Lee, and we all went through an entire box of tissues as we wept with joy and marveled at so much goodness.

‘Batkid Begins’ is a crowd-funded documentary playing this week at Slamdance, and it even inspired legendary poster artist Drew Struzan to come out of retirement and create a poster for the film. And even though it’s been over a year since Miles Scott and the people of San Francisco warmed our hearts, his story is still inspiring to so many, as evidenced by not just the documentary, but Roberts’ interest in bringing this story to a wider audience—hopefully it’ll inspire even more acts of intense kindness.
