San Francisco's local superhero Batkid touched the lives of millions across the globe. His charming moves on the street as Batman's little avatar caught the eye of celebrities and politicians. Ben Affleck and Christian Bale praised the little superhero for his efforts.

"Wasn't that fantastic?" Bale told Vulture as he broke into a smile. "This little kid, oh my God - what a wonderful day for the little fella! It's just fantastic, seeing all those people who were out there to support it," he added.

"I looked on the news and I saw this headline and thought, 'What's that?' And I saw all the pictures of him running around and saving people. It's so touching," Bale said.

Bale asked Batkid's name. "What's his name, Miles?"

"He must have been bewildered! Hopefully, later on, he'll be able to look back and say, 'Oh my God, how amazing.'"

Another dude - Ben Affleck who is the next Dark Knight also loved the performance of Batkid. Affleck took to Twitter on Saturday. "Batkid. Best Batman ever," Affleck tweeted, clearly a hardcore Batkid devotee.

Close to 12,000 volunteers and fans lined the streets of San Francisco on Friday and welcomed Miles as Batkid. He has been battling lymphoblastic leukemia and wanted to spend the day as the Caped Crusader. Make-A-Wish organised the event and made Miles' dream come true.

Miles mother told KNTV-TV that her son loves to be a superhero. She added that he is one because he is defeating a terminal disease.

On Thursday night, a bat signal went out and shined on the side of Miles' hotel. Police Chief Greg Suhr issued a statement on a local newscast that sounded like a plea.

"Please, Caped Crusader, we need," Suhr pleaded.

Later, Batkid saved a damsel in distress, defeated Penguin and Riddler (two powerful villains) and saved Gotham city. Thousands watched in awe and even Police men took pictures of Batkid on the streets of San Francisco.

Way to go, Batkid!
