Sometimes, an actor or actress shows up on set without doing much preparation and somehow makes a role work. Then, there are those who put so much time and effort into bringing a role to life on screen, they live as the character they are portraying.
This level of effort doesn't often go unnoticed, especially when it comes at the cost of a dangerous amount of weight gain or loss, but there are plenty of things actors have done to make their roles particularly special, but hardly anyone ever noticed.
These are the things they did to prepare for a role, or it's something they did while acting out their part, but the thing they did was either of such minutia, it couldn't be noticed, or it didn't matter because it was done so well.
The best examples of this sort of preparation are the ones nobody notices. If you think about it, wouldn't you rather be pulled into a portrayal and think it's entirely real than notice something blatant and obvious? Mera's wig in Aquaman comes to mind, but that's more on the costume department than the actress.
Regardless, there are plenty of examples of actors going to extreme lengths to play a character, and these ten are the most insane of them all.
10. Robert Patrick Found A Way To Keep His Eyes Open In T2
Robert Patrick's T-1000 is one of the best portrayals of a robotic assassin ever put to screen, but the level of detail the actor put into the role is even more impressive than you may know. If you go back and watch the film, you'll notice what you're about to read, but odds are, you didn't notice it before.
Whenever the T-1000 fires a weapon, it doesn't blink. This is completely unnatural, and as anyone who has fired a gun will tell you, the natural response our body has to pulling that trigger is to blink.
Not blinking is incredibly difficult, and like sneezing, it's just one of those things our bodies do, but a person can train themselves to keep their eyes open. That's exactly what Robert Patrick did; he trained for months to fire a weapon without blinking, and hardly anyone even noticed.
That being said, had he blinked when he fired a weapon, it would have been entirely noticeable. Arnold got to wear shades to avoid this problem, but the T-1000 didn't put anything on his face. Had he blinked, it would have been strange... after all, why would a robot made of liquid metal blink when it fired a gun?
