Yes.
(from IMDB)
John Connor: I need a minute here. You’re telling me that this thing can imitate anything it touches?
The Terminator: Anything it samples by physical contact.
And he used Goldstein and Paxton in “Titanic”. In these 3, Ms. Goldstein portrayed 3 different ethnicities: American (T2), Hispanic (A2), and Irish (Titanic).
Just watched the opening scenes again. When the T-1000 arrives, a cop is driving by and stops to investigate the lightning. This cop is definitely NOT played by the T1000 actor Robert Patrick. As he’s looking at a circular hole in a fence, a naked Robert Patrick comes up behind him and hits him in the abdomen. He bends down over the maybe unconscious, but given what we later find out probably dead, cop, and in the next scene is walking to the police car in a police uniform.
The next few scenes are of Arnie & the T1000 each trying to find John Connor - the T1000 by talking to his foster parents. They both track him down at a mall, and right up until the shooting starts, you’d really think the T1000 is actually the human sent to protect him from Arnie.
So the default face he uses most of the movie is the one he actually arrived with, unless it was a homeless guy he killed in the few minutes before the cop showed up.
Interesting that he copied the cop’s clothes only. I would have bet money that his Robert Patrick-ness was copied from the cop as well.
Well, they couldn’t have done it in CGI, but they could’ve used miniatures or some other old school technique, but it probably wouldn’t have looked as good.
Ignoring the “he never touches a cheetah” aspect, a cheetah runs faster than a person because of specialized muscles. Given the liquid nature of the T-1000, I’d guess that he could reach top speed in practically any form and turning into a cat, horse, antelope or whatever wouldn’t make him any faster. He does do a decent job to trying to catch up with the car in the one scene. Gets his “hand” blown off for his trouble but he does catch the car.
Like the man said, I think the idea was for an audience to mistakenly figure this guy is the next best thing to Kyle Reese: another resourceful and cunning resistance fighter sent back to use the minimum required amount of force to accomplish his mission, someone who shows up naked but promptly acquires weapons and clothing while dispatching any obstacles in his way as he moves to intercept the Terminator tasked with murdering the legendary Connor – who our hero is sensibly desperate to locate and protect, by any means necessary.
Seeing a nude Robert Patrick swiftly overpower that cop and then ask all the right questions while wearing a sidearm when dressed like a policeman – man, that fits.
It’s not a plot point in the theatrical release; that sequence, filmed with Linda Hamilton’s twin sister, is a deleted scene.
The “never touches a cheetah” part is irrelevant. We know he’s able to form himself into simple non-human shapes likes blades and grabby-crowbar bits. I’m not saying to become an actual cheetah, I’m saying to shape himself into some physical shape other than bipedal human in which whatever “muscle force” he’s able to generate produces maximum forward velocity on the ground. Which is why I’m thinking a long-legged quadraped of some sort.
This is where the prototype-ness comes in. If Skynet had time to fully develop the project, the T-1000 would have a ton of pre-programmed shapes in its arsenal (super-fast-runner, super-wall-crawling-climber, etc.) that it would change into when speed or climbing was important, as opposed to camouflage and appearing human.
Bill Paxton was also in True Lies.
From your point of view…I don’t know tech stuff.
Part of the problem is also that the human the T-800 looks like is the other T-800 who is wanted for wiping out a police station in the first movie.
But the reason is that Sarah, John and Uncle Bob are trying to blend in and hide from the T-1000. If they are walking around with some sort of obvious half-man half machine cyborg from the future or at the very least, what looks like a bloody mess of a guy who was shot sixteen times, it is going to attract unwanted attention, possibly drawing them into a conflict with the police (where Sarah or John could be killed or injured). The more attention they attract, the more likely the T-1000 will be able to acquire them.
Some terminators are flesh covered. The terminators in the future war scene don’t have flesh because they aren’t infiltration units. They are just regular old infantry models.
Doesn’t make sense to cover your endoskeletons with flesh if they are just going to go wading into shrapnel and 40 watt phased plasma rifle fire.
Considering every computer programmer I have ever met in my life, I seriously doubt that option 5 would ever even be considered. 
On the other hand, it would bring new meaning to the phrase “meat shield”.
Bill Paxton, Jeannette Goldstein, and Lance Henriksen were also all in Near Dark. So Goldstein has played four ethnicities: American, Hispanic, Irish, and vampire.
Also, Bill Paxton is the only person to have been killed by an Alien, a Predator, and a Terminator. (Lance Henriksen might also be included if he was in the police station during Arnie’s rampage and can be considered “killed” in Aliens.)
Lance Henriksen was absolutely shot by Arnie in Terminator. He jumps out in the hallway, yells “Hey!” and shoots Arnie. Arnie calmly turns around, and shoots both his rifle and shotgun at Henriksen. We don’t see him collapse, but there’s no chance Arnie missed. So unless he avoided bleeding to death until the EMTs arrived, he’s dead as Dillinger.
Definitely killed in Terminator, more like grievously injured and asking to be euthanized in Alien 3.
He was a robot. Would a robot ask to be euthanized? Could you even call him injured, or would “damaged” be a better term?
You’ve never met a female programmer? 
He prefers the term “artificial person”.
Well, preferred.
