Well, the lesson came with the ALIENS figures.
Drake was painted iwth red hair and a fake mustache that when painted away, he looked just like the actor. Ripley, while not perfect, is overly femmed from Hot Toys but with a solid repaint can look close to Sigourney Weaver. Hot Toys Terminator looks nothing like what's seen on screen because they had to extend the damage to the face so much there was zero of Arnie in it.
Even Dutch was original painted with horrible camo and apps and if it weren't for his very defining features, probably wouldn't have looked a bit like Arnold, but the mouth and cheeks give it away. HT either has always tried to get his likeness rights or was aware of all the grief about his likeness not being clear from the early leaked images and got the rights, either way, they finally secured the rights to do Arnie's portrait without tricks.
