At a press conference for his latest comedy, Pineapple Express, Seth Rogen said his next film might be saddled with the dreaded NC-17 rating.

"I would say it's pretty dirty language-wise," said Rogen of Zack and Miri Make a Porno. "It does not seem that dirty to me. To me, it literally does not even register in my brain anymore."

Here's an example of what you can expect from the movie:

In the movie, two friends find their friendship tested when they decide to make an adult movie. Rogen thinks the sexual suggestions in the flick may freak out the ratings board, even though it appears to be fine with the violence of films such as Hostel.

"I don't know why. To me, it's a mystery that you can show these horrific things, but not some sexual stuff which everyone does," Rogen said.
