I found one!
Once in a while my local Blockbuster gets a batch of old VHS tapes in. I check every few weeks. When I checked the other day and asked, "Have you gotten any more VHS tapes in for sale?" the ladied repied with a definite edge in her voice, "Yeah, you could say so. 5,041 of them!" as if she had personally been the one who made shelf space for them and unpacked all the boxes. They have Hollywood Video store labels on them. It took me three trips to the store to look at them all.
AND ON THE FINAL TRIP, THERE ON A BOTTOM SHELF, COMPLETE WITH ORIGINAL BOX WAS "The Killer Elite" (1975) in its PG version, copyrighted 1984 by CBS/FOX.
Unbelievable, Number 1 on my wish list, sitting right there before my eyes!
So, they're out there folks. You just have to keep your eyes peeled.
By the way, in the party scene, this being the PG release, the incredibly beautiful girl sitting with Robert Duval has her dress arranged properly in the close-ups. But in the opening shot of the party, the whole-room view, her breasts are exposed and visible. Oops, the re-editors slipped up. I should say, one is visible and the other is blocked by her knee.
