Watch: Nathan Fillion As Star Trek's Captain Kirk (Video)
Comic-Con officially kicks off tomorrow, with the hype only beginning.
I love being in front of a big group of people who are already super-excited; their adrenaline's flowing. There's a really positive wavelength of energy. And then they laugh at my crappiest jokes. For me, that's Comic-Con.
Fillion also has a guest role in the Marvel Studios Guardians of the Galaxy movie.
