Quote (TV Line)
Firefly (Science Channel, 8 am – Tuesday, 2 am) | This Firefly marathon, which begins with the film Serenity, features a naked Nathan Fillion, a pre-Mad Men Christina Hendricks, a pre-Nikita Melinda Clarke, and a kick-ass Summer Glau. What more can you ask for?
Edit : It starts with the first episode called ‘Serenity’, not the movie. the writer had it confused with "Serenity" the movie. The movie won’t even be aired in the marathon.
