In movies how do they make two of the same person..And make them touch eachother?

Answer 1

They use special screens and lighting techniques.

Answer 2

Good question.

We've two fine examples ... The Parent Trap with Haley Mills in the 60's and the flick with same title with Lindsay Lohan the 90's.

They often simply use a body double for touching, you can see just one performers back -- yet they are dressed the same. It's skillful and delicate work creating the illusion.

At one time they used "blue screen" and now they use "green screen" to make the performer be on the camera with the background equaling nothing ... then they'd insert that image into another scene.

Answer 3

With very difficult and tedious computer compositing.
They shoot each carefully choreographed performance against a blue or greenscreen (so they can add just ONE background later), then they do the same with the second performance.
They scan the film into the computer, then a compositor lines up each "actor" to the other.
It requires a lot of tweaking, because as you would imagine, the actor could not possibly have done it exactly right.

Answer 4

I really don't know how movies are actually made; but I think the way they can get actors to touch each other has a lot to do with the money the actors will make for doing such scenes.

Answer 5

they get a body double so when they come to replace the double with the other guy it looks realistic.

Its all computer generated.
