In Season 7 when Gage and DeSoto go to San Francisco the opening credit scene which pans along the San Francisco-Oakland Bay Bridge is the same scene from the closing credits on The Streets of San Francisco (1972). The same footage was sometimes used in the opening credits of "McMillan and Wife."
The fires on Pier 5 caused some legal problems for Emergency's production company. The San Francisco Chronicle reported that the production company was cited for violating local air pollution rules. The article quoted a spokesperson from the Bay Area Air Pollution Control District saying that "It's an illegal burn, no question about it," who also said that open burning is only allowed for a limited set of agricultural purposes, certainly not for adding reality to TV shows.
