San Francisco Turned Into Gotham City For 5-Year-Old ‘Batkid’ [VIDEOS]

There was no San Francisco, Calif. on Friday. Instead, SanFran morphed into Gotham City, all so one boy battling leukemia could have his wish: to be Batman.

Warning: You may want to grab tissues. Even President Obama was in on the wish.

Five-year-old Miles is a kindergartner, and he is in remission after battling cancer since he was 18 months old. Instead of battling cancer, today he was battling crime.

All this is happening because of what happened after Patricia Wilson of the Make-A-Wish Greater Bay Area Foundation sent an email in October asking for some volunteers to help give Miles his wish. She's part of a national organization that grants children with life-threatening illnesses their wishes. Her chapter opened in 1984 and now grants about 300 wishes a year.

But this wish request was different. Wilson's email request to turn San Francisco into Gotham City went viral. And between 11,000 and 12,000 volunteers came to contribute their efforts, whether it was acting, being stage crew or assisting in a myriad of other ways", according to NBC.
