Every time a(ny )character says the company name, 'Fiscal Dynamics,' the line's been looped (dubbed) from the original (Financial Dynamics). This was done, most likely, due to a real company by this name being identified between the completion of the script, and post-production. But, in the first part of the 4th season 2-part episode, (The House on Willis Avenue (1978)) Richie Brockleman congratulates Rockford on his work on the 'Financial Dynamics' case, which probably means the name-change dubbing didn't happen 'til after this - most likely when the series' ended its network run, and went on to syndication.
One of the (very) rare times during the entire series' run in which a crowd's seen being 'penned-off', as it were, so as not to affect a scene. Not only that, but right when Arnold Love opens the door to Broadway Plaza a businessman can be seen behind the 2 of them who's obviously not an actor, but who just recognized James Garner. When Jim and Arnold Love get to the bottom of the escalator, they walk to the (viewer's) right and a rather large crowd can be seen (notably, a blonde woman in a red dress with a cut-out top at the forefront) standing next to the 'up' escalator.
In this episode Jim Rockford asks to speak to 'Lt. Becker', but Dennis Becker doesn't become lieutenant until Kill the Messenger (1978), when Dennis learns his long-time association with Rockford's what's held him back from becoming a Lieutenant.
Stuart Margolin, who played Angel Martin on the show, provided the voice for the taped message heard at the beginning of the episode.
After Jim first meets Arnold Love, he gets the check (its dated 10.22.74). Even though it's a fictitious prop-check, its date would be pretty accurate for when this scene had been filmed, as it's usually about 6 weeks - 2 months on average during regular season production for a TV episode to go from production, and would appear 'real' upon the first airing (which was 20 Dec, 74)
