Question

What are the top 10 highest grossing adult films of all time. School project-need answers?

Answer 1

Don't know all of them, but "Deepthroat" has to be #1.

Answer 2

You might wish to learn to use a search engine.  Just type your subject in the Search_______Web Search box at the top of this page.  Follow the links.  It's called "research," and it's part of school work.

Besides the first answers, look up "Behind the Green Door."

Answer 3

I don't know about the other 8 but the top 2 would have to be Deep Throat and the original Debbie Does Dallas.
