8. Wayne Hall

The exterior of Wayne Hall is filmed at the Hudson County Courthouse in Jersey City, built in the early 1900s in the Beaux-arts architectural style. In both Joker trailers, while a film of Charlie Chaplin’s Modern Times is being screened inside Wayne Hall, a mob of people with clown masks and signs are fighting with police.

The Hudson County Courthouse has been used in filming locations before, for Law & Order, for example. The beautiful building was saved from demolition in the mid-20th century and added to the National Register for Historic Places in 1970.
