How about a "Star Wars" recast? I have a few ideas.
Twilight Sparkle as Luke Skywalker
Flash Sentry as Hans Solo
Sunset Shimmer as princess Leia
Princess Celestia as Obi-wan Kenobi
Fluttershy as Chewbacca
Rarity as C3-PO
Sweetie Belle as R2-D2
King Sombra as Darth Vader
"Hypnotized" Crystal ponies as Stormtroopers
What'cha think?
