the charismatic conman in "White color" or in "Magic Mike." He takes a new turn in "The Normal heart," who plays a "New York times" reporter who falls in love with an AIDS activist. Shutting up is my problem. Why do you write all of that? I'll bet you gobble it up every day. I know ten people who have died. When I came to you, it was only one. I'm sorry. And Matt Bomer joins us now. Welcome to "Gma." Incredible performance you gave right there. And this was something -- this was a role you've been drawn to for a long time. You read "The Normal heart" as a teenager. Yeah. I read the play for the first time when I was 14 and living in suburban Texas. It just blew my mind. I had no idea that this was going on. And no one around me was talking about it. It completely changed my world view. And getting to be a part of it 20 years later is just, like, the opportunity of a lifetime. That's one of the things that makes this so special. It is 20 years later. We're not in the middle of the crisis. We get to view it with the perspective of history. I think it's scary to think about it as a period piece. AIDS hasn't been eradicated. And there's 6,000 new cases of it every day. 30 years of the original production, it's getting a life on film as a really profound gift. You actually got to work a bit with the playwright, Larry Kramer. You all worked together, filming a big party seen on the day that the supreme court struck down the marriage act. Larry, in so many ways, is somewhat responsible for that moment, to be there with him on that day was just completely surreal. And one of those few times in your life when you feel like you're really in the right place at the right time. And that's part of something really special. And to see him there on that day, was just unbelievable. Of course, we all saw you in "Magic Mike." Lara insisted I bring up "Magic Mike." You had to go through a physical transformation? Was it 30, 40 pounds? I stopped weighing myself after 35. I thought the number wasn't important. We had a couple weeks to go. Matthew was incredibly helpful. I reached out to him. He gave me pointers. And I did my own thing, too. And he was very kind. Are we going to see a "Magic Mike 2"? That's the game plan. I'm happy to be along for the ride. Those guys were the first people to bring me to the party. I'll be there however they want to have me. You brought a lot to "The Normal heart." Thank you very much. It premieres on HBO Sunday, may 5th.
