Terminator 2: Judgement Day - Three Hands Are Better Than Two
In the part where the 2nd Terminator is chasing Arnold and Linda in the helicopter... If you watch carefully, the 2nd Terminator is shooting with both hands while a stage hand is holding and steering the wheel from the bottom.
This isn't a slip-up. If you look closely, you can see that the 3rd hand is coming out of his abdomen - the second terminator had grown another hand to fly the chopper.
They're right. The T-1000 adapted to the setting. He needed three hands to fly and reload, and since he can morph, presto. Now don't you wish you could grow an extra arm once in a while? ;)
Yes, but why would you steer with your knees if you could grow a 3rd hand? Besides, it's not like you didn't wish you had a 3rd hand while you were eating that whopper.
sure everyone would like to grow a 3rd arm or a 3rd leg (not even going there :)) for running, but you can argue your way out of most artistic license issues in films by saying it would ruin the suspense e.g. the t1000 did not need to stab through the lift/elevator ceiling he could have slipped into it from above much earlier and perhaps made an armful of sharp needles then sprayed the entire room, or when the truck blows up in the flodd control he could have pretended to be small parts of the debris hubcaps etc but instead the makers prefer to use a rubber tire that the t100 has to double check. These are not bloopers essentialy but tools used by directors etc to make viewers inquisitive!
Actually there are 4 arms.
Two for weapon and magazine
And the two others for flying the helicopter
One controls the Cyclic Stick and the other controls the Collective lever.
