Showtime has officially cast the leads for their upcoming fictional drama Billions, which “takes a forensic look at the world of high finance by tracking the approaching collision between two titanic figures.” The network announced today that Emmy winners Paul Giamatti and Damian Lewis will star in their drama pilot, which begins filming in early 2015.

The “titanic figures” in Billions are U.S. Attorney Chuck Rhodes and hedge fund king Bobby “Axe” Axelrod, which will be played by Giamatti and Lewis respectively. The series will be written by Brian Koppelman, David Levien and Andrew Ross Sorkin, and Showtime announced Friday that Limitless director Neil Burger has signed on to direct the pilot.

Billions will reunite Giamatti with Sorkin, whose book inspired the HBO’s original movie Too Big To Fall which Giamatti co-starred in and earned an Emmy nomination for. This will also be the 47-year-old actor’s second time working with Burger, as the two collaborated on the 2006 film The Illusionist; Levien and Koppelman acted as producers of that film. The series will continue Giamatti’s recent attempts to break into television; he also earned an Emmy nomination for his appearances in Downton Abbey earlier this year. Lewis will be making his return to Showtime after winning a Golden Globe and Emmy for his portrayal of Nicholas Brody on the network’s Emmy-winning drama Homeland.

The upcoming series marks the latest network attempt to see if the success of Leonardo DiCaprio’s The Wolf of Wall Street, which dominated box offices last year, can be replicated for television. CBS is also planning an untitled Wall Street-themed drama written by Justified’s Taylor Elmore, and Fox Television Studios is adapting Kevin Roose’s best-seller Young Money as a potential drama series.
