Did they not have the budget to hire a copy editor?
I just watched the trailer for Clint Eastwood's new movie Hereafter, and whoa. Major typo in the text of the trailer--they spelled beginning "begining". I would link to it, but I can't find it anywhere online--the typo isn't in the official trailer. How do you make a mistake like that when you only have about 15 words to read?
