The 28-year-old actor stars in the upcoming horror thriller by Niels Arden Oplev and for the role as medical student Marlo, Dobrev and the rest of the cast had to undertake training, reported Contactmusic.
"We went through a rigorous medical boot camp to learn about everything to do with reviving a human in a dire situation - CPR, how to use the defibrillator, how to get heart monitors, and if that's not working, how to physically check the body," Dobrev said.
Dobrev stars alongside Ellen Page, Diego Luna and James Norton in the movie, which is a sequel to the cult 1990 movie of the same name.
