SAN FRANCISCO (KGO) --The documentary about the Bay Area's favorite caped crusader premiered Thursday night in San Francisco.
A convoy of Lamborghinis carried many of the people who helped grant the wish of 5-year-old cancer patient Miles Scott, who wanted to be Batkid.
Red carpet arrivals for "Batkid Begins: The Wish Heard Around the World" started at Sundance Kabuki Cinema on Post Street around 6 p.m.

The documentary will open in select theaters Friday.
