i don't believe HT can do anything good today in licenses i'm interested in (aliens and predators = Tsang, terminator = bubbleheads with bad sculpts and rotting pleather), except for Robocop (magnificient work all three, if not for rotting rubber), so i voted Robocop.
though i hope they won't revisit it, i bought too many silver Robocops already
Definitely Alien.
It's my favourite franchise and one of my favourite movies (Alien).
The aliens have never been done accurately by Hot Toys, the Colonial Marines were released ages ago, and it's a very popular franchise with collectors.
My all time Grail is a rock solid Indy from Raiders that finally, finally nails Ford's likeness. Hopefully someone does it with the new film coming out.
USCM from Aliens with better head sculpts, First Blood - Rambo with a better head sculpt, some Soviets from Rambo II and III, the full rescue team from Predator, Keyes and Garber from Predator II, Bennett and Gen. Kirby from Commando. I could go on and on....
Planet of the Apes.... so I voted "Other". I would love to see them tackle Dr. Zaius or Cornelius, especially since their sculpting skills have improved since their gorilla offerings. And those gorilla do sell for a fairly high amount in the secondary market.
