SEATTLE — Constanza Romero Wilson, wife of the late Pittsburgh playwright August Wilson, will be on hand Sunday at the Academy Awards to represent her husband, who received a posthumous nomination for his screenplay to “Fences.”

Based on his Tony Award-winning play, the screenplay written by Wilson in the late 1980s finally came to the screen, directed by and starring Denzel Washington, more than 10 years after Wilson’s death in Seattle in 2005.

“I think that he would be ecstatic to have the movie out, for his work to have that kind of representation in Hollywood,” Romero Wilson said last week by phone from Los Angeles, where she’s attending award ceremonies and events leading up to the Oscars.

“I think that he wasn’t really that caught up with stardom or any of that stuff. He had a razor-sharp focus on his own work. But he would have been excited about the fact that millions of people now have seen ‘Fences’ — more people in America have seen ‘Fences’ than ever came to all those shows on Broadway. He would also have loved the fact that this story has touched so many people.”

Romero Wilson described the “Fences” film, which received three additional Oscar nominations, as uncompromising in its celebration of Wilson’s poetic dialogue. “The language is front and center. Denzel started from a point of view of paying homage to August, and of making him proud. And (Washington) spoke about just having and feeling love, throughout the process of ‘Fences’ — for each other, for the characters, for August, and for paying him respect. I think he would have loved (the film), no question about it.”

She recalled the origin of Washington’s involvement, at a long-ago meeting at the Wilsons’ Capitol Hill home. Now the actor/director is shepherding a massive project: bringing the remaining nine of Wilson’s American Century Cycle of plays to the screen, as part of a contract with HBO.

Romero Wilson is working on publishing a collection of her husband’s poetry, and hopes to see more productions of Wilson’s one-man autobiographical play “How I Learned What I Learned.”
