Actors and crew members working on “A.D.,” the follow-up to Mark Burnett’s and Roma Downey’s “The Bible” miniseries, were in for a major surprise last week while filming in Morocco.

Downey told TheBlaze that her team was working on a scene depicting Peter and John in front of the Sanhedrin — an event that can be found in Acts 4 in the Bible — when actors Adam Levy (who plays Peter) and Babou Ceesay (who plays John) noticed something curious directly overhead in the sky.

“There they could see clouds had formed in a completely blue sky in the perfect shape of a cross,” Downey said. “Everyone was stunned and filming stopped, as iPhones came out and everyone was snapping pictures.”

The “Touched By an Angel” actress and TV producer said that it was “a moment of awe,” with everyone on set claiming that they believed it was a sign and a blessing to see a cross form in the sky.

“It certainly energized a tired, hardworking crew for the rest of the day and reminded everyone that we were being watched over as we are working hard to bring the Book of Acts to the screen,” Downey said.

The actress added that she shared the image with well-known Florida megapastor Joel Hunter, who reminded her of Peter’s sermon in Acts 2:19, during which the apostle quoted the prophet Joel.

That verse reads, in part, “I will show wonders in the heavens above and signs on the earth below, blood and fire and billows of smoke.”

Readers may recall that Downey and Burnett openly discussed other miracles that they say unfolded while filming “The Bible” series as well. Read about those here.

“A.D.,” a 12-part miniseries, is set to premiere on NBC on Easter Sunday, which is April 5, 2015.
