The Human Rights Campaign invites New Yorkers and visitors to the Big Apple to film their own video for the New Yorkers for Marriage Equality campaign this Sunday in Manhattan.

The first "pop-up video" event will be held Sunday from 11 a.m. to 4 p.m. at Gansevoort Plaza in the Meatpacking District at the intersection of Nine Avenue with Gansevoort and Little West 12th Streets, not far from the elevated High Line park. Notable attendees will include two-time Tony nominee Gavin Creel of Hair, Nick Adams of Priscilla Queen of the Desert, and the cofounders of Broadway Impact, Rory O'Malley (The Book of Mormon) and Jenny Kanelos.
