Award-winning producer and actor Kevin Spacey will deliver the keynote speech at the American Institute of Architects National Convention 2016 in Philadelphia.

The show is set for May 19-21, and Spacey will speak on the first day.

In 2014, he was named one of Forbes’ “Most Powerful Celebrities” and was the first online-only television series star to make the list, according to a release from AIA. Most recently, he was awarded an Honorary Knighthood by Queen Elizabeth II.

“Perhaps no one in Hollywood works harder to defend the value and integrity of the arts,” the release reads. “He believes that the creative arts are essential and the lifeblood of a nation. And through his foundation, he’s providing opportunities for a new generation of writers, actors, and filmmakers. We all have something to learn from Kevin Spacey.”
