I'm not gonna lie- you know one movie that I'd love to see ponified? Apollo 13. It's kind of meta inceptiony if you think about it: a ponified version of a dramatized version of a thing that actually happened. Actually, I'm pretty sure that's not meta or inception. Nevermind. I have some pony trailers if you're still interested, though.
1) Wreck-It MAC Trailer 2 + Cast change
2) My Little Sucker Punch
3) Ponytheus Trailer
