Beloved actor Nathan Fillion has had a fairly charmed career ever since his breakthrough role as Captain Malcolm Reynolds in Firefly almost 15 years ago. Since then, he’s become a geek convention favorite, appearing in niche projects like Dr. Horrible’s Sing-Along Blog, making cameos in major films like Guardians Of The Galaxy, and all the while keeping an incredibly successful mainstream career, primarily as the star of the long-running ABC series Castle. At the beginning of this week, he unveiled a new Uncharted short fan film in which he plays swashbuckling treasure hunter Nathan Drake—a role that fans of the franchise first pointed out he was perfect for more than a decade ago.

When he got on the phone to do AVClub’s 11 Questions feature, he was in the midst of a very busy press day. Fillion’s Uncharted director Allan Ungar was there listening in, and even amid some very earnest answers, the actor couldn’t resist using one of the questions to have a little fun at his new director’s expense.
