American Gigolo (1980)

1991 Paramount Hi-Fi VHS: Perhaps a bit less detailed and with more background hiss than you'd expect from a 1980 magnetic mono mix, but this still sounds good overall.

2024 Arrow UHD Blu-ray: The mono here is a remix. It's not a straight reduction of the stereo/5.1, but it is very plainly not the theatrical mono track. A few content discrepancies, which are totally insignificant on their own and are more just evidence that this is a remix:

• 16:34: There's some background dialogue (bad ADR) that fades out early in the VHS mono but continues in the Arrow mono/stereo/5.1.
• 40:34: A different, more forceful sounding, Foley effect in the Arrow mono/stereo/5.1 as the handcuffs hit the table.
• 57:40: More rattling in the Arrow mono/stereo/5.1 as Gere opens the door

The real issue with the remixes is that they sound harsh. All background noise has been aggressively removed. The EQ of the entire film, really, is headache-inducingly V-shaped. The music is also of higher fidelity than the dialogue.
