As to why we have Fett blasting Luke in one and Sandra Bullock in the other, well thats easy, I'm secretly in love with her. Actually the TV was just on and it happened to be the proposal. After a few shots I decided to add Mr. Fett instead. Now as to Master Chief, well yeah he wasn't in the films, but the helmet needed a safe place. So it got placed kinda low but still displayed until that spot gets filled with more SW stuff.
Lastly, I love my Jawa cat.
