'How to Make Money Selling Drugs' deals a new documentary blend

'How to Make Money Selling Drugs' producer Bert Marcus seeks to make documentaries that are both socially conscious and financially successful.Documentaries typically can be split into two camps. There are those designed to entertain -- penguins in snow, Justin Bieber in concert -- and sell tons of tickets. Then there are works -- bleak stories about hunger, pollution, genocide -- more intent on scoring partisan points than box-office records.
