"I'm trying to understand why nobody gives a shit that we're dying," Mark Ruffalo's character, Ned Weeks, screams in the preview.
The cast includes Ruffalo, Matt Bomer, Taylor Kitsch, Jim Parsons and Julia Roberts, with appearances by Alfred Molina, Joe Mantello, Jonathan Groff, Denis O’Hare, Stephen Spinella, Corey Stoll, Finn Wittrock and BD Wong.
The teaser may only be 45 seconds long, but it packs a wallop as characters played by Ruffalo, Roberts and Kitsch fight to be heard.
The HBO Films original premieres 8 p.m. May 25 on HBO.
