Actor-director Rob Reiner has suggested America is ready for gay marriage.

The 64-year-old Reiner is a board member of the American Foundation for Equal Rights (AFER), the group formed specifically to challenge the constitutionality of Proposition 8, California's 2008 voter-approved gay marriage ban.

AFER's legal challenge resulted in a federal judge declaring Proposition 8 unconstitutional last year. (The ruling has been appealed.)

On Monday, 8, the Dustin Lance Black (Milk) play based on the 13-day trial, had its star-studded Broadway premiere.

During an appearance on MSNBC's Morning Joe, Reiner talked about the play's premiere, his group's legal challenge and Proposition 8.

Reiner suggested marriage equality was on the brink of acceptance.

“The country right now is virtually split 50/50. I think the latest polls show that gay marriage is over the 50 percent mark. We're just barely over 50 percent,” Reiner said. “And it's interesting because people would say, 'Well why bring a federal court case at this point?' Well, when Loving v. Virginia, which is back in 1967, which said that blacks and whites could not get married, almost 70 percent of the country was against the idea of interracial marriage. So, we're much further along in terms of the public accepting the idea of gay marriage than they were at the time accepting interracial marriage.” (The video is embedded in the right panel of this page.)
