It is true that they made money off this movie by having it shown at 3 different theaters with two showings in each theater. The first two showings were packed with 200 people each. If the other 2 theaters both had 100 people each showing then 800 people paid for this movie.
If producers got at least 4 for each ticket then they would have got around $ 3,200 or more from the movie.
They did say that DVDs would be free as you would download the file then burn it to a DVD yourself.
