Warner Bros. debuted the emotional trailer for it's upcoming movie Batkid Begins: The Wish Heard Around the World, which follows the story of Miles Scott, who was diagnosed with Leukemia at 20 months old. His cancer is now in remission.
Miles had one wish
-- to be the real Batman -- so Make-A-Wish turned San Francisco into Gotham City in 2013, and then 5-year-old Miles got to fight crime with Batman as Batkid for a day.
"One of his doctors told us that with this disease, they just become like a fighter." said Nick Scott, Miles' father. "They fight for life."
"And so I think he sees the good vs. evil battle in superheroes," added Nick.
The event drew thousands, and caught the attention of everyone from Ben Affleck to Pres. Barack Obama, who uploaded a video to vine saying, "Way to go, Miles. Way to save Gotham."
We have to see this movie!!
Batkid Begins will be in select theaters June 26.
