Los Angeles has become Gotham City as the Bat-Signal glows at City Hall.
Hundreds of fans — some in costume — cheered Thursday night as Mayor Eric Garcetti and Police Chief Charlie Beck turned on the Bat-Signal.
The iconic circle of light with a bat-shaped silhouette glowed on the City Hall tower.
The ceremony honored Adam West, who played the Caped Crusader in the campy 1960s TV series.
West died last week at 88.
