Millions remember the story of the young San Francisco boy fighting cancer who got to be Batman for the day. Now he is back. Julia Roberts will be producing and starring in the movie Batkid Begins, a remake of the movie Batkid Begins: A Wish Heard Around the World, according to TV Guide.

The documentary film, Batkid Begins: The Wish Heard Around the World, premiered on Jan. 24 at SlamDance Film Festival. Roberts will rework the film with Lisa Gillan and Marisa Yeres Gill, states Variety, an entertainment news company. Dana Nachman, the original director, will act as the executive producer along with Dan and Josh Braun of SubVersion, a variation of Submarine that is being introduced at Sundance.

The movie showcases 5-year-old Miles Scott living out his dream of playing Batman, an American superhero. While he is battling leukemia he is able to save Gotham City, all due to the Make-A-Wish Foundation, a nonprofit organization that grants wishes to children with life-threatening diseases.

Little Miles Scott stole hearts in November 2013 when he took to the streets of San Francisco, California with the help of the Make-A-Wish Foundation and the city of San Francisco. The 5-year-old leukemia patient was given the task of keeping the city by the bay safe and no one could have done a better job.

Several San Francisco citizens stepped in as volunteers to help make this 5-year-old’s dream come true. The San Francisco police department and other city officials also lent a helping hand leading up to the event. The Make-A-Wish Foundation, after talking to the Chief of Police and the Mayor’s Office, were able to find two batmobiles and discovered what Miles enjoyed the most about Batman and contemplated what days would be best to operate around his treatment and his parents’ work schedules.

San Francisco was converted into Gotham city for the day, as junior Batkid stepped in to help. The day had started with a request for Miles, from the police asking for help, that disrupted the ABC 7 news. Accompanied by an adult Batman, Eric Johnston,  Batkid participated in several rescue events, and in the end was presented with the key to the city by the mayor at City Hall.

The Make-A-Wish Foundation put out a request to the public for help and requested volunteers in this event. Through social media and the web, the requests were heard and roughly 20,000 people attended the event at City Hall. Millions of people around the world talked about the day that Batkid saved San Francisco.

The event helped raise awareness of the Make-A-Wish Foundation. It helped to increase the number of people willing to volunteer for the organization and an increase was seen in donations in all areas globally. The group has also seen an increase in referrals and other services since the affair took place.

Since the original event took place, Batkid has been doing his best to give back to the organizations that aided him in fighting his leukemia according to the Huffington Post. This includes The Batkid Fund that donates 100 percent of its proceeds to the three charities that assisted him.

The documentary is about Batkid and his efforts to save San Francisco. It explores the efforts leading up to the big event and documents all the scenarios that took place that day. Julia Roberts was touched after seeing the documentary, which lead to her directing and starring in the new movie about Batkid.
