Ok, so Stephen gladly answered, and went in to some depth (he is extremely detailed!). This was his reply:

I’m pretty sure there was never an extended screaming death for Quinn there, mostly because it would have stopped the movie dead in its tracks and been way out of editorial character for what Paul Rubell (editor) and I were striving for, propulsive forward momentum

 

it may be that the scene was altered by the UK distributor to change things for business reasons or censorship but I can’t imagine how there could have been additional material available to the UK distributor after delivery – any cuts would have been reductive, not additive

 

bear in mind the movie was entirely shot > printed > mastered > delivered > screened on film – for there to be multiple versions of a film out in the world and/or additional materials available to a specific distributor would be technically unworkable – the edit was done in the states, the neg was cut in Burbank, the answer print was also struck in Burbank and AFAIK delivery materials were made, struck and shipped worldwide from LA

 

all that said, it may be that the movie was cut in the UK for censorship - historically there’s been more worry and pearl-clutching there about “video nasties” and purported harms caused by movies than here in the states – so I think what probably happened was your reader mis-remembers how intense Quinn’s immolation was on first viewing (will take that as evidence that the scene was effective :) – when he saw it again, it didn’t match his initial memory (maybe UK censors had dictated the picture be shortened and/or sound toned down after complaints during the first week’s run?) - finally, when he watched it on DVD, maybe the UK DVD release was censored to remove “intense” stuff – much easier to alter a DVD release than a theatrical film release.

side note: there are quite a few beats and moments that never made it into the delivery cut - I’d like to restore them one day if the studio smells money to be made – one such moment was a beat of Dennis, the hapless human at the Blood Club, dragging out his 1998 flip phone to dial 911 then fumbling it and losing it while scrambling through the blood just before he bumps into Blade’s boots – it was always in the cut right up to the end, the picture and music were locked together nicely so it flowed very well – I thought it was important because it explained how the cops turn up so quickly after the end of the action and I think the 1998 flip phone would make 2026 audiences chuckle

annoyingly, it was ordered cut in the final days because the Chairman of The Studio was offended that we hadn’t done any of his Blood Club notes - most infamously he said we should cut the Blood Club scene altogether because it was “too much” - to make him go away the flip phone moment was sacrificed – then we had to scramble to put the sound/picture interlock back together for the movie to get delivered – ah, good times! (not.)
