You're in the SyFy Channel's shoes. You have a large scale and prohibitively expensive makeup job that has to be done in order to transform a bunch of "extras" into zombies. What do you do if you can't afford a crew of professional makeup artists to do the job?

Read the books Universal Studios has tried and failed to censor on Amazon.com...
And read these books at another location where Universal Studios executives and its stealth marketers won't be able to post negative, misleading (stealth marketed) reviews of the books via them purchasing candy and Rogaine Foam on Amazon.com (allowing them access to the Amazon book review section) and not actually buying and reading the books. I'll leave the other 150 global locations under wraps for now.
