“The Normal Heart,” originally a Tony-award winning play by iconic gay activist Larry Kramer, reached a brand new audience when it appeared on HBO as a film directed by Ryan Murphy earlier this year.

Now, in honor of the film’s release on DVD and Blu-Ray tomorrow, August 26, we’ve got an exclusive clip of Kramer discussing the real life events that inspired it.

In the clip, which can be seen above, Kramer, Julia Roberts and other stars from the film speak about the pushback that Kramer received when he began to speak out about HIV in the early 1980’s.

Kramer notes, “The gay world did not want to know about this illness — that’s where I got the reputation for being a screamer. It was the only way you could get anyone to pay any attention. You know, ‘You dumb assholes! It’s a plague!’”

Watch the clip above and get your own copy of “The Normal Heart” on DVD or Blu-Ray, which both include an exclusive behind-the-scenes look at the true story that inspired the film, featuring cast and crew interviews, as well as a Digital HD copy, in stores tomorrow.
