'The Normal Heart': HBO debuts intense new teaser trailer: Watch

the-normal-heart-teaser-trailer-hbo.jpg HBO's original film "The Normal Heart" will be as intense as it will be dramatic.

Thanks to a new teaser trailer the cable channel just dropped, the film -- starring Mark Ruffalo, Matt Bomer, Taylor Kitsch, Julia Roberts and Jim Parsons and about the onset of the HIV-AIDS crisis in New York City in the early 1980s -- promises to keep viewers on the edge of their seats as the characters struggle to understand what's killing them and why no one is helping them get the word out. "The Normal Heart" will shine a spotlight on what gay activists went through trying to expose this new epidemic despite the government's denial.

Watch the intense new teaser trailer below:



"The Normal Heart" premieres Sunday, May 25 at 9 p.m. ET on HBO.
