This took a lot of time!

This is pretty darn cool (and nerdy)! Especially at the end when the Superman theme kicks off and the DC guys start showing up.

Stop action with action figures has got to be grueling. Limited mobility and all. Just think of the time involved...
Assume it's 10 "frames" (pictures) per second
Movie is 8:42 = 522 seconds
522 * 10 = 5220 pictures
30 seconds to take each picture = 156,600 seconds = 2610 hours
If you worked 8 hours a day we're talking about 326.25 days!

At 8 frames per second you're still talking 261 days!
