NBC announced at its upfront presentation to advertisers Monday that it has greenlit a new pirate-themed series, "Crossbones” and may air the "Munsters" update, "Mockingbird Lane," by midseason 2012-13.

NBC Entertainment Chairman Bob Greenblatt said the “Mockingbird” pilot, starring Eddie Izzard (pictured) in the Grandpa role, will be shot next month and could be on the air soon if it goes well.

“Crossbones,” about the pirate Blackbeard creating a society that is more civilized than the British Empire, comes from "Luther" creator Neil Cross.

The network unveiled its 2012-13 slate to advertisers Monday at Radio City Music Hall in a presentation that included perfromances by “Smash” stars Katharine McPhee and Megan Hilty and “The Voice” winner Jermaine Paul.
