Exactly. Judging by behind the scenes, Nathan really just seems to try to enjoy himself, as he has a tendency to play pranks on everyone he works with at some point (I advise watching some videos of those from Firefly trying to answer questions at conventions. Most times anyone from Firefly is on one, Nathan rings them, and on one, he appeared from backstage, surprising everyone)
No, I haven't, but I will keep a look out. I always love finding new films!
