Sam Heughan, best known for his role in the drama series "Outlander," will be portraying iconic American actor Paul Newman in an upcoming film.

The Scottish actor, 39, confirmed the news on social media Tuesday. "So excited to share this!" he wrote. "Paul Newman was immensely talented, generous and an American icon. So fortunate!"

The film, which is wrapping filming soon, is a biopic of actress Patricia Neal and her husband/author Roald Dahl, who are being played by Keeley Hawes and Hugh Bonneville, respectively.
