Batkid film will be really beautiful: Julia Roberts

Los Angeles: "Pretty Woman" star Julia Roberts has revealed she is developing an adaptation of a documentary about a six-year-old Batman fan who took over San Francisco, California for a day.

Cancer survivor Miles Scott earned the name 'Batkid' in 2013 after organisers from the Make-A-Wish Foundation recruited 11,000 volunteers to turn the streets of San Francisco into the Caped Crusader's fictional Gotham City, so the child could live out his superhero fantasies.

The project has been titled 'Batkid Begins: The Wish Heard Around the World'.

"We're just super excited, my sister and I have a production company, Red Om Productions, we were lucky enough to see this documentary and we loved it and I think it will be a really beautiful movie," Roberts, 47, said.
