We've seen a few looks at 'American Horror Story' creator Ryan Murphy's forthcoming HBO tearjerker 'The Normal Heart' already, but the latest full trailer for the star-studded AIDS drama is easily the most intense, and emotionally intriguing yet, particularly for fans of its star-studded cast.

In case you hadn't already heard of the May 25-premiereing film or its stage origins, HBO’s ‘The Normal Heart’ follows ‘The Avengers‘ star Mark Ruffalo as activist Ned Weeks, one of the first to draw attention to New York’s HIV-AIDS epidemic of the ’80s. Based on the Tony-winning Larry Kramer play of the same name, the drama also stars Julia Roberts as Polio survivor and physician Dr. Emma Brookner, ‘White Collar’ vet Matt Bomer, ‘The Big Bang Theory‘ star Jim Parsons reprising his role of activist Tommy Boatwright from the 2011 stage version, as well as Taylor Kitsch.

Also present for the first time in any of the trailers is former 'Glee' and current 'Looking' star Jonathan Groff, who looks to be in dire straits by the beginning of the film. Our latest look at 'The Normal Heart' also tones down the music to delve into the character work a bit more, which is sure to have Emmy voters talking as much, if not more than last year's 'Behind the Candelabra.'

See what all the hype is about with the latest 'Normal Heart' trailer above, and tell us in the comments if you'll tune in May 25 for the big reveal!
