"It's a great show. It's all about accepting imperfections and accepting people for who they are," said Sook, who is young enough to remember the Disney version when it first came out.
While he has done shows with extensive makeup and costuming, Sook said Shrek takes him to a new level.
"I wear a full film-quality prosthetic. I have a foam-like cowl they pull on me and four prosthetic pieces that are put on with an adhesive that cover pretty much my whole face. It takes a solid hour and 15 minutes every day," he said.
Sook, who grew up in Texas, first stepped on stage when he was 4. His mom was directing a local production in which his two older sisters were performing, and another young actor dropped out.
"I was like, 'Put me in!'" he recalled. "And I've been doing it ever since."
By high school, he knew he wanted to make theater his career. As for his sisters, one is a working actress in New York and the other took a different career path - she's a lawyer.
Sook landed the Shrek role this past summer, when he was working on another show. Actors were expected to learn their parts on their own, so Sook worked double duty to complete his summer duties and prepare for "Shrek."
"We were expected to show up that first day off the book, with our parts completely memorized," he said. "We rehearsed nine days in New York and three days in Anchorage (Alaska) before we opened there."
Sook said he's enjoying seeing the country. In Alaska, he saw the Northern Lights. This week before coming to Charleston, he saw Niagara Falls.
"It's been phenomenal," he said.
