The pool hall scene with Magnum, T.C., Rick, Mr. Harms (Donald Gibb) and Mr. Jansen (Dick Durock) was filmed on location at the Cebu Pool Hall (Hotel and River Streets), which appears to have been a rather notorious Filipina hangout for many years. The hall was part of the H.Y. Wong building (built in 1906), which at the time of this episode was one of the last remaining wood-flame structures in the downtown Honolulu area. The building was razed in 1992 and replaced with low-income housing.
