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?
Oz could have been better, but there's still some fun to be had here. As a bonus, it does look absolutely amazing in 3D if you choose to see it that way.
What do you think? Will you go see Oz the Great and Powerful?
