As one of the leading actors on Starz’s new time-travel romance series “Outlander,” Scottish actor Sam Heughan suddenly found that both himself and kilt were under scrutiny. Heughan said of his recent U.S. tour to promote the show, “I always find it quite strange when people want to know more about the actor than they do about the show.” He added with a laugh, “There were a lot of questions about the kilt and what’s under it.” The premiere of “Outlander” last month drew 5 million viewers, the largest multi-platform audience in Starz history.
