"The Dovekeepers" stars Cote de Pablo and Diego Boneta reveal that while the CBS miniseries is a faith-based project that doesn't mean that they kept it tame.

Last month, Cote joked with ET that she was getting all the romance in "The Dovekeepers" that she didn't get on "NCIS." When she and co-star Diego Boneta stopped by ET, she admitted that there was plenty of passion in the series, but with reasonable boundaries.

"I wouldn't say it's sexual," Cote said. "I'd say it's sensual."

The one-of-a-kind TV event produced by Mark Burnett and Roma Downey ("The Bible") is based on Alice Hoffman's bestselling historical novel about the Siege of Masada in 70 C.E. where 900 Jews stood their ground against Roman armies after being forced out of their home in Jerusalem and ensconced in a fortress at a mountain in the Judean desert. The project will recount the events from the perspective of a few extraordinary women with different back stories who share a common bond for survival. Cote plays Shirah, a healer accused of practicing witchcraft.

Diego nicknamed Cote "The Dove Whisperer" for the way she handled the birds on set, and Cote gave up a few tips.

"The key is: don't be anxious, because the birds will feel the anxiety and they will be nervous and you won't be able to do much with them," Cote said.

The project also stars Rachel Brosnahan ("House of Cards") and Kathryn Prescott ("Finding Carter") in the title dovekeeper roles.
