A glimpse of the film, which is still in the works, has been posted on YouTube.
The Bay Area filmmakers behind the project are turning to fans worldwide to raise $100,000.
Proceeds from the film and soundtrack will go to the Batkid Fund, which is supported by the family of 5-year-old leukemia survivor Miles Scott, and will benefit Make-A-Wish and other charities.
The filmmakers hope to launch it in Nov., the anniversary of when San Francisco made Batkid's wish come true.
