My grail list these days would be pretty much the same it has been for years. The following done to the highest modern standards:
Clint Eastwood, both as Dirty Harry Callahan, and also from any, or all, of his (non musical
) westerns. Hell, there are so many Eastwood roles I'd buy in figure form, even beyond those. Everything from Where Eagles Dare, and Kelly's Heroes, through to Any Which Way, Heartbreak Ridge, In the Line of Fire, and Gran Torino. So many possibilities from all across his career.
Blade Runner - With a sequel on the horizon, I wouldn't be surprised if some company finally cracks this one in the not too distant future. Just the act of the sequel being made would have necessitated the fractured rights of the original film being properly defined and sorted, one would imagine, so never say never. I can hope, anyway.
X-Files Mulder & Scully and Millennium's Frank Black. Not sure the last one would sell, but that doesn't make me want it any less. I'd be very tempted by Skinner, Doggett, CSM and (Millennium's) Peter Watts, too, but I don't know how many others would be.
Mel Gibson as Mad Max from all three original films. Yeah, that'll happen...
Hicks, Hudson, Vasquez and Bishop from Aliens. Boggles my mind that Hot Toys hasn't revisited the Colonial Marines, given what they could (potentially) deliver now.
Figures of Cult TV shows Red Dwarf (Rimmer, Lister, Cat, and Kryten), The Prisoner (just Number Six), and Blake's 7 (at least Avon, Blake, Villa and Servalan). None of which would ever, ever, ever happen, being way too niche. And from the other side of the pond I'd be awfully tempted by Babylon 5, Farscape, Xena, and Buffy/Angel as well, though the latter is probably the only one with a legitimate chance.
Videogames wise, I still want a John Marston from Red Dead Redemption, Ellie and Joel from The Last of Us, and Sam Fisher from Splinter Cell.
Yeah, don't think many of my dreams are coming true any time soon.
