Good news, everyone! Saturday is Free Comic Book Day, and one of the comics available for free contains Serenity and Star Wars stories, both written by Zack Whedon. The best part is you can read this preview of the Serenity comic right now.
An easter-egg in Firefly's pilot episode reveals that it takes place in the same universe as the Alien series. It appears the anti-aircraft cannon Mal uses to shoot down an Alliance fighter was manufactured by Weyland-Yutani Corp.
So does this mean Weyland-Yutani provided the Browncoats with weapons to fight the Alliance? Whose side do you think they were on in the Unification War?
