I watched Willy Wonka and the Chocolate Factory a few weeks ago, soon after Gene Wilder's death. Watched extras on the DVD (which I've owned quite a few years). The movie was financed by Quaker Oats, who came out with the Wonka bar and were convinced to finance the movie (for a couple million dollars) which came out at the same time as the candy bar in hopes that sales of the candy would take off. The movie was pretty much a flop and so was the candy, which tended to unexpectedly melt. They had to pull them from the stores. So it said in the on-DVD documentary. The movie has become a cult classic over the years, but AFAIK, not the candy bar. I've never seen one. I didn't know it still existed.
