This comes straight from the screenwriter's (David Steinberg) MySpace blog. Apparently Universal has decided to drop the Presents from their American Pie titles. Read his statement for the info.
Presents?There has been much debate over the last few months whether Universal will break with the "American Pie Presents" formula on this movie since I named my script simply, "American Pie: Book of Love" (with a colon instead of "presents"). The notice of tentative writing credits was issued today and they seem to be calling it "American Pie: Book of Love" which is a major victory for me. It's actually not a major victory at all-- more of a micro victory, but we writers care deeply about such things.
For the record, I got sole credit on the movie which is not surprising since there were no other writers.
Congratulations, David!
