Calling all San Diego sailors: If you’ve got some free time Tuesday evening, TV network TNT is holding an open casting call for extras for its Navy-themed show “The Last Ship,” according to a Monday post on the Naval Base San Diego Facebook page.

From 2 p.m. to 8 p.m., sailors are invited to drop in to Building 45 at the Recreation Center NBSD, in the Blue and Gold Conference rooms. Applicants must bring an I-9 form (downloadable here) and written permission from their chain of command to participate.

Also, you have to be on authorized leave or liberty, so don’t go during work hours.

“The Last Ship” is currently filming its second season, set to premiere this summer.

If you watched season one, you know the story: Cmdr. Tom Chandler (Eric Dane), commanding officer of the fictional destroyer Nathan James, has returned from deployment to a world where 80 percent of the population is dead or dying of a highly contagious super-virus.

Chandler and virologist Dr. Rachel Scott, played by Rhona Mitra, might have the cure, if they can stay safe and alive long enough to distribute it.

For more info on the show, check out our interview with Dane. If you can’t stop by Jan. 13, you can contact the casting director directly. More info on that here.
