“Terry Crews Saves Christmas” is more than an attention-grabbing title: For several families, he really does.

The “Brooklyn Nine-Nine” co-star and NFL veteran travels to several cities — along with designer Vanessa Deleon and chef Dean Sheremet — to help people who have hit snags in planning holiday celebrations in a new miniseries that The CW will air over four consecutive nights starting Tuesday, Dec. 20. Crews puts his big personality to amusing work for citizens who are quite surprised when he shows up at their doors, sometimes in guises such as a ballet outfit.

“The producers from a group called Electus had an idea to put a series of holiday specials together,” the affable Crews explains, “but they didn’t know who to go after. Someone said, ‘Terry Crews,’ and it got revamped to be me saving holiday disasters. And I was with it, man. I’ve got five kids and I’ve been married 27 years, so I’ve had my share of Christmas disasters and faux pas, big-time problems that I had to solve myself. And I love the holidays, so this was perfect for me.”

Crews knows “the holidays are a big deal.”

“For those who are intimidated by it, we try to help them get with it or lean into it,” he says. “We come in and pick out what the problems are, and in 48 hours, we revamp their home and their food and the way they do everything. The families have the love, but a lot of times, they just don’t know what to do.”

The situations are quite varied, as Crews has learned anew from making the show: “We’ve been to Chicago, L.A., all over the place.”

While entertainers are used to making Christmas shows out of season so that they’ll be ready to air at the appropriate time, the civilians involved in “Terry Crews Saves Christmas” had to make a pact with Crews and his crew to play along. Still, he admits there are telltale signs.

“We started filming before Halloween, so we were like, ‘What are all these Halloween decorations doing up at Christmastime?’ And we just kept going with it,” he says. “One good thing is that we break the fourth wall here, and I talk to the camera. It’s like a reality show of a kind you’ve never seen, showing you all the behind-the-scenes things while we’re doing it. It’s just a free-for-all. (Those visited) might have expected a Martha Stewart type, but to see a 250-pound African-American wearing an elf costume ... they take a lot of pictures.”

Not only does Crews maintain he’d be game to do “Terry Crews Saves Christmas” again, he says he’s ready to spread the concept to other holidays.

“We could just keep doing this,” he says. “Anytime you have any kind of celebration and you don’t know what to do, we can do it. And the funny thing is that I don’t even know what to do; that’s why we have the professionals along. I’m here to be the spirit, to bring the energy and the joy, because I understand it — but I’ve made all the mistakes. If Christmas has a spirit animal, it’s me.”
