Gold Dust Orphans captain Ryan Landry — known for putting on gender-bending shows at Machine nightclub — celebrated the opening of his Huntington Theatre Company production “M” by hosting an after-party at South End restaurant 28 Degrees on Wednesday night. Revelers included Samantha Richert, who plays “Olga,” costume designer Scott Martino, Huntington artistic director Peter DuBois, and Landry.
