BillionsThere are a lot of reasons to watch Showtime's upcoming drama "Billions" — will you groan if we say a billion reasons? — but a new teaser showcases the two biggest ones: Paul Giamatti and Damian Lewis.

Lewis plays a smug, rich hedge fund manager who will do whatever it takes (even if it's illegal) to make money. "When did it become a crime to succeed in this country?" he wonders. Giamatti is a U.S. Attorney who isn't going to let 1-percenters like Lewis trod over the rules and the rest of society.

"Billions" already had us at "starring Giamatti and Lewis," but the teaser is just dynamite. Seriously, we're already blown away with just one brief minute of footage.

Among the other reasons we're excited about the drama are the other cast members: Maggie Siff, Malin Akerman, and David Costabile.

"Billions" will debut on Showtime sometime in early 2016.
