Boardwalk Empire Wiki

Arnold Rothstein (played by Michael Stuhlbarg), affectionately nicknamed "The Big Bankroll", is the main antagonist of Season 1, and the biggest, most powerful gangster in the country at the beginning of the series. Despite his status, he is known for his calm and polite demeanor as well as his fondness for gambling and picky food habits. He is based on the historical figure of the same name.


As a consummate gambler, strategic genius, and forward-thinking intellect, Rothstein never bets unless the fix is in. "The Big Bankroll" has incredible resources at his disposal, and will go down in history for his most famous, and possibly most impressive fix - the rigging of the 1919 baseball World Series. It is Rothstein's activity which brings Agent Nelson Van Alden to Atlantic City, and brings the heat on Nucky Thompson. After Nelson Van Alden investigates Nucky's operations, he diverts his attention to him, believing Nucky to be the "bigger fish" of the two. Rothstein’s gang also consisted of famous gangsters of the future, such as Lucky Luciano and Meyer Lansky.

Memorable Quotes[]

  • “There was a man once—I don’t recall his name—frequented the billiard parlors downtown. He made a comfortable living wagering whether he could swallow certain objects, billiard balls being his specialty. He’d pick a ball then take it down his gullet to here, and regurgitate it back up. And one evening, I decided to challenge this man to a wager: ten thousand in cash for him to do the trick with the billiard ball of my choosing. Now, he knew I’d seen him do this a dozen times, so I can only surmise that he thought I was stupid. We laid down the cash, and I handed him the cue ball. He swallowed it down, it lodged in his throat, and he choked to death on the spot. What I knew and he didn’t was the cue ball was one sixteenth of an inch larger than the other balls—just too large to swallow. Do you know what the moral of this tale is, Mr. Yale?" "The moral of the story is that if I cause a stranger to choke to death for my own amusement, what do you think I’ll do to you if you don’t tell me who ordered you to kill Colosimo?” ("The Ivory Tower")

  • "I've made my living, Mr. Thompson, in large part as a gambler. Some days I make twenty bets, some days I make none. There are weeks, sometimes months, in fact, when I don't make any bet at all because there is simply no play. So I wait, plan, marshal my resources, and when I finally see an opportunity and there is a bet to make... I bet it all." ("Two Boats and a Lifeguard")

  • "Mr. Doyle, why am I talking to you?... But why am I calling you? Why is that even occurring? If I had my liquor on the timely basis your employer promised... if in fact I could reach your employer, who now seems to think acceptable business practice is to disappear for days on end, this conversation would not be taking place and that would make me... very happy. I want what I paid for. I want it now. And I don't ever want to find myself chatting with you again. Is that clear?" (Blue Bell Boy)

You have failed to deliver! And now, owing to your inability to manage your affairs in New Jersey - a state I have little interest in or affection for - you expect me to start a war? In New York? Where things actually matter?"
