I was just thinking of a film I kind of watched many years ago. I don't remember much of the details but I do remember that..it seems ..by accident (the first time anyhow) a person ends up in the factory machine that makes chocolate. Well eventually the chocolate becomes a HUGE success and people are strangely addicted to it. Demand is so high the maker I think figures out what that "secret ingredient" was and decides to keep incorperating it into his candy. Seems it's someones job to toss people into the candy machine.
Title?
That would be
CONSUMING PASSIONS, with Jonathan Pryce and Vanessa Redgrave.
