Blue,
Since you were so kind as to award me a prize in the past, I disavow any interest in such 'competition' here...i.e. this is provided gratis! Oh...that means 'no charge', Blue, even if you and IM force decide to accept my mission. Of course, I shamelessly admit that in private you can certainly provide me a copy of the movie. I'm joking!
The Dirty Harry scene is beautiful, but it does not address your specific 'one shooting, one asphyxia' concept directly, so maybe I'm 'adding' this thought to his....lol. I love his Suzy outfit, though I may put Brandy in tight jeans and a tank top or even an elegant 'bare-midriff' outfit as she talks with her Boss and Suzi walks in.
Sure, Suzi can shoot her, I love it....lol. And since I personally prefer a knife to asphyxia, I love the idea of Brandy throwing a knife INTO Suzi's belly, I like that, after she's been shot! Personally, I'm not as into the 'multiple' stabs that become rather 'violent' or 'crazed' almost, but one knife throw and maybe a second thrust after Suzi falls to her knees beside Brandy, that would work for me if one death does not 'have to be' via asphyxia.
Though I might suggest a bit of a struggle over that gun first, with it of course discharging its first shot into Brandy's bare stomach....the first shot, that is.
And the Boss walks in after Brandy is dead, while Suzi is bent over the body. A nice strangle from behind with Suzi expiring gently over Brandi's body would be a rather nice 'touch', I would think....or a few nice 'touches' depending on where the always-creative Producer decides to align those two draped bodies for the final camera views.
And of course the Suzi Strangle could be proceeded by some gratuitous hugging and mini-fondling of Suzi from behind by The Boss, in congratulations for her success but with her unaware of the double cross to come, maybe just as their lips are to meet, with him still behind her and her head leaning back on his shoulder, the Boss can begin the Strangle from there. I like that touch of eroticism.
And since you're into providing value for your customers, Blue, a second version must be produced that has Suzi die first, by being shot by Brandy.
But the catfight idea is always a winner, with some ample body touching and rolling over each other's breasts and all the subtle erotic ways that fight can ensue. Maybe with some clothing that gets disheveled a bit during the struggle, or even torn, but who wants to ruin good clothes?....LOL!
As Suzi is even astride Brandy, while wrapping Brandy's own silk scarf around Brandy's own neck.....pulling, pulling.....Brandy gasping and legs bouncing and arms rattling and entire BEING straining to rise, heels drumming on the floor as Suzi takes her closer...and closer...and closer.....to drawing her last breath.
But before the final 'tug', Brandy's scrambling hand of course finds the gun on the floor....or in some 'stupid' place like in Suzi's rear waistband....lol......and shoves it RIGHT into Suzi's belly through that white blouse...and FIRES.....Suzi jerking UPward, back straight, pelvis 'subtlely' grinding DOWN into Brandy's 'sex area'.....Suzi's eyes WIDE as her body FREEZES in that position on her knees with rigid back straight up.....as Brandy puts about 3 more into her, one into each breast and one more into her belly....and Suzi falls directly over Brandy's still gasping and straining body.
A couple of moments for Suzi's quivers to stop, and Brandy to regain the strength to roll Suzi off of her, Suzi falling onto her back, slowly and gracefully, with nice leg view and up that short skirt, too.
And she just leaves Suzi lie there for a moment, looking, as she gains the strength to rise to her knees beside Suzi.....before The Boss appears suddenly behind her with the garotte he slips immediately around her neck from behind. Brandy STRAINS backward, against his chest, midsection and pelvic area dipping downward to touch Suzi's body, as Brandy's back arches back, back, back....her eyes growing wider.....until the final pull of her neck....and her own collapse, this time on top of Suzi for the final camera pans.
I do not agree to your prior comments about 'no compensation' required. Since these concepts are time-honored and with those two spectacular Women will be a wild commercial success, I demand my normal compensation, no less. I won't take more, either, mind you, but not ONE penny less than for the last idea I gave you.
That's my Final Answer, Blue. Sometimes even a Negotiator has to 'hold the line', you know?
Not that any financial renumeration could ever be worth as much as Bluestone Video, but....
well, this time I must insist on my 'normal' compensation. Please advise if this is acceptable.
If you try to fight me on this, Blue, I will NOT take it lying down.
Humph! So there! (he's shaking in his mukluks, I can see it!)
ah, heck, I'm like everybody else, I want to SEE these two together! And in more than one scene!.....LOL.
And the Strangler is not to be you, Blue; I could not 'stand' seeing you derive that much pleasure from your work.
Of course, if that is a non-compromise 'position' for Blue in this movie, I am always open to negotation. I would begin by asking for....oh, say....double my normal compensation if you insist on personal involvement with 'these women'.
Subtle Sandi
So, feel free to write in a killer at the end to finish off the apparent catfight survivor, if necessary.
I'm really looking forward to acting with Suzi again. She is an amazing talent!
