So according to I Watch Stuff, Christopher Nolan got the idea for INCEPTION from a Don Rosa story featuring Donald Duck and the Beagle Boys.
But according to Chris Sims, it was Calvin and Hobbes that gave Nolan’s dream epic its inspiration. Which to choose? And apparently, Matthew Vaughn didn’t want X-MEN FIRST CLASS to resemble either Donald Duck or Calvin and Hobbes and had to change 12 pages of plot so Cyclops didn’t suddenly put on a domino mask and start robbing banks.
NOTE: Despite numerous attempts we still haven’t seen INCEPTION, and it still hasn’t been entirely spoiled, but writing these things is hard!!
