Boardwalk Empire went out with a bang Sunday night -- and not just with the shocking demise of Jimmy Darmody.

The season two finale of HBO's Steve Buscemi-led, Prohibition-era drama posted a season high for the series, drawing 3 million viewers with its initial airing at 9 p.m. and picking up an additional 834,000 viewers with its 11 p.m. encore for a total of 3.8 million.

That marked a season high for the series, which averaged 2.7 million viewers this season for its 9 p.m. airings, and premiered in September with 2.9 million viewers (again, excluding encores).

The finale dipped slightly from last season's, which drew 3.3 million viewers for its 9 p.m. airing.

Sunday's Boardwalk Empire finale was followed at 10 by a preview of HBO's upcoming horse-racing drama Luck, which averaged 1.1 million viewers. The series, which stars Dustin Hoffman and Nick Nolte, will receive its proper premiere January 29.
