Leonardo DiCaprio, a prominent environmentalist, is taking the Volkswagen emissions scandal to the big screen.

The scandal is less than a month old, but DiCaprio’s production company Appian Way has acquired the rights to a book about it. The book hasn’t even been written yet – it’s merely a proposal by author Jack Ewing.

Though DiCaprio will produce the film, it’s unknown whether or not he’ll star as well.

The scandal that rocked the auto industry saw Volkswagen admit to fitting its diesel vehicles with software so they could beat emissions tests.

The software, known as a ‘defeat device’, allowed the cars to beat lab tests, but it was revealed that the cars emitted 40 times what they tested at when driving around in the wild.

The scandal caused Volkswagen’s stock price to plummet and the company’s CEO Martin Winterkorn was forced to resign. Volkswagen has publicly announced plans to spend at least $7.3 billion on fixing the emissions issues, and the company’s U.S. CEO Michael Horn was recently grilled by Congress about said plans.
