standout night for HBO’s “Euphoria” at the Creative Arts Emmy on Sept. 4, it was an especially joyous one for actor Colman Domingo, who scored his first major industry win for his moving turn as teeenager Rue’s (Zendaya) patient sponsor Ali on the controversial drama. The ubiquitous actor, recently seen on TV in “Fear the Walking Dead” and “The Twilight Zone” among his many credits, is a fan favorite on “Euphoria,” and credits his Emmy-nominated costar Zendaya for creating such a good vibe to work on the HBO drama.“We have such a connection, which is very deep and complex,” Domingo said backstage following his Outstanding Guest Actor in a Drama win.
