The opening Sarajevo scene was shot on a street by the Woodward's Building in Vancouver, Canada.

The Art Deco entryway belongs to the Marine Building, a block away at Hastings Street and Burrard Street. Government House in a later scene is the Vancouver Art Gallery (originally the Vancouver courthouse) with Hotel Vancouver in the background.
