"The Normal Heart" Full Trailer : We've already seen a few preview clips for "The Normal Heart," the HBO film based on the Tony-Award winning play by Larry Kramer about the HIV/AIDS crisis that hits New York in the early 1980s, but a full length trailer has just arrived. Directed by Ryan Murphy ("American Horror Story," "Glee"), "The Normal Heart" stars Mark Ruffalo as a gay-American man who tries to combat the lack of knowledge regarding the disease, which is seen as a "gay epidemic" by the public after it's first discovered. In the trailer below, we see Ruffalo desperately try to rally the masses, including his partner (Matt Bomer), brother (Alfred Molina), and friends. "The Normal Heart" looks to be a heartbreaking story about a period in our history that was shrouded in chaos and doubt. The cast, which includes Taylor Kitsch, Julia Roberts and Jonathan Groff, should help.
