Other rumors claim that Bobby Cannavale, who appeared in Season 3 of 'Boardwalk Empire' as crazy Gyb Rosetti, will be the leading man in the new Terence Winter series. However, no official word has been released about any of these rumors.

Stepping back into 'Boardwalk Empire' the final season will consist of eight episodes. This time around, the spotlight will be set on Nucky Thompson who remembers his days in Atlantic City and tries to scheme up plans for a soon to be post-Prohibition era.

On a point of interest, show-runners for 'Boardwalk Empire' promise an unforgettable series finale, where each and every character will be met with judgement for their actions.
