I have also wondered what sort of dramatizations could come out of Mars, Inc, though I also wonder if there are weird classified twists that won't come out easily. Or at least if you were writing the fictional dramatization there's a rich room to play with the idea of what was really going on in that Chocolate Factory. With Mars, Inc. a private family company headquartered in McLean, VA, it's almost hard not to imagine some complicated history with the CIA as well. The UK branch spin off sounds like a reverse Kingsman/Statesman plot if you assume some spycraft in the company's history.

(Rival Hershey's ties to Pennsylvania history/culture similarly leaves ideas for National Treasure-style conspiracies in the chocolate world in the early history of control over the national identity.)

Free silly plot ideas for Hollywood or a graphic novelist hoping for Hollywood adaptation opportunities.
