X Rated Version

So there's an unofficial x-rated version of this movie called "Girl Trouble (2010)" which even has it's own rather empty page here on imdb; http://www.imdb.com/title/tt1789769/. It's an adult film where the plot is nearly identical, except for the fact that the sex of the characters is reversed (Dane Cook in the movie is essentially played by Kaylani Lei) What boggles me is that after watching about 30 minutes of it, I tried to find anywhere on the internet that made a connection between the two to confirm my suspicion, but there wasn't a single website, and the movie makes no attempt to credit the movie for it's inspiration...
