I'm willing to have my illusions destroyed [how was this illusion done?]

It must be so simple that I can’t see it, but how does this illusion work? What am I missing? I’m willing to have the illusion spoiled for the chance to understand what’s happening. Any help?

Clever editing.

Identical twins.

It is a hoax.

“This was originally a Kickstarter project by students at the Rochester Institute Of Technology to “create a myth” by producing a short film in time for the Imagine Rochester festival, on May 4th, 2013.”

It’s not a hoax or trick. A trick is something a whore does for money.
