WATCH: Chilling 'Selfless' 2015 Movie Trailer [VIDEO] Ben Kingsley Takes Over Ryan Reynolds' Body In New Thriller From Director Tarsem Singh

Imagine a world where the old and/or dying have the capability of transferring their respective consciousness into the body of a younger person. In the new sci-fi thriller Self/Less (or Selfless), director Tarsem Singh introduces this concept with utterly terrifying implications. Sir Ben Kingsley portrays a wealthy man that is dying of cancer, who is convinced to take part in this procedure by Matthew Goode. Ryan Reynolds serves as the younger body, but how did this young man become this empty vessel? Check out this brand new trailer fro this thriller below!

This would definitely be a huge step in preserving life and getting closer to immortality, but at what cost? We learn pretty clearly in this first movie trailer that Goode's character is not the compassionate type. After successfully transplanting Kingsley's consciousness into Reynolds, some flashbacks of this body's life show up in his mind, causing him to wonder what truly happened so that he can have this new body.

How far would we go for such advancements in technology? It turns out that the answer to that will certainly leave us all in a cold sweat. We can find out in theaters on July 31, 2015.
