In the film's first scene, Riggs accidentally sets off a bomb that destroys the ICSI Building. The ICSI Building was actually the former City Hall building of Orlando, Florida, located at the intersection of Orange Avenue and South Street in Downtown Orlando. Warner Bros. decided to use the destruction of the building in the film, and as a result paid $500,000 for the demolition. From August to October 1991, the production crew fitted the old Orlando City Hall building featured in the opening scene with carefully placed explosives to create the visual effect of a bomb explosion. Bill Frederick, then mayor of Orlando, Florida, was the policeman who sarcastically claps and said "Bravo!" to Murtaugh and Riggs after the explosion.
