* Hoban "Wash" Washburne in Firefly and Serenity
** Captain Malcolm Reynolds
Wikipedia says "Gina Torres and Sean Maher, both also Firefly stars, as well as Amy Acker, James Gunn, Seth Green, and Felicia Day will guest star."
So in other words it's the big Firefly / Angel reunion web show, and looks like it might be good fun. Unfortunately it's pay to view, so I think I'm going to wait to see if it comes out on DVD or something.
