Watch: Say Goodbye To 'Boardwalk Empire' With 30-Minute Doc 'The Final Shot' With Martin Scorsese, Steve Buscemi, More

Next Sunday, HBO will lower the curtain on "Boardwalk Empire." After five seasons of bootlegging, prostitution, assassination, and power moves from some of the underworld's seediest characters in the Atlantic City of the 1920 and 1930s, the lights will be shut off. So to get you prepared, HBO has unveiled a must watch thirty-minute documentary.

The appropriately titled "The Final Shot" brings together executive producer Martin Scorsese, writer Terence Winter, and key cast members (Steve Buscemi, Gretchen Mol, Kelly Macdonald, Michael K. Williams, Stephen Graham and Michael Stuhlbarg) to share their recollections on the genesis of the show, shooting the series, and much more. It's insight from the on-the-ground players who have lived with the show for the past half-decade, and it's fascinating stuff for those who have been following the adventures of Nucky Thompson and co.

The series finale of "Boardwalk Empire" airs on October 26th. Watch below.
