"Breaking Bad". Not a movie but series.

Replace drug with any other product and the ingenuity of Walter White to scale the operations, hiring people, shifting operations to different locations, responding to competition makes it interesting.

An amazing TV series about a talented young man who bails out on his ambitions, and becomes a family man, only to grow old at an unsatisfying job, and finding himself facing his mortality, at which point he decides to change his life and achieves his true potential.

"Top Boy" qualifies as well in that respect (a new, and quite likely final, season has just been released). While not exactly as well-known as "Breaking Bad", it not only offers an insightful perspective on the drug trade itself but also on a specific London subculture.

Fundamentally, that show is about business and entrepreneurship. Sure, the industry might seem more than just a little shady and its methods often are ruthless, but basic business principles still apply (to quote one of the main characters: "Buy cheap, sell dear.").
