Sigourney Weaver tears up over emotional role as mother of gay son

Sigourney Weaver stopped by the AM studio today to discuss her movie "Prayers for Bobby." The Lifetime movie, based on a true story and now on DVD, tells the story of a close-knit religious family that is shattered after the son reveals he is gay.

John Roberts and Kiran Chetry sat down for a poignant interview with Weaver to talk about her experience playing the deeply conflicted mother, Mary.

Watch the interview to see just how emotional Weaver gets talking about the role. "So moving to me to hear Mary talk about how she realized later on looking at his baby pictures, God had wanted him to be gay," Weaver says of when she met the mother.

Weaver also talks about the recent repeal of  the military's “don't ask, don't tell” law and why she is celebrating.
