7 things you probably didn't know about the making of season 2 of 'The Boys'

"Actually, it's pretty functional and it works pretty well," the actor told Entertainment Tonight. "But the problem is the battery pack has a noisy motor, so we've got to take it off when we're shooting."

If the cooling system method sounds familiar, it's because some Marvel stars use the same tactic for their superhero costumes.

"My introduction into the world of performing was singing but that was when I was much younger and that was what I initially wanted to do," the actress told Entertainment Tonight. "I wanted to be a singer and then it turned into acting."

Moriarty added that showrunner Eric Kripke wanted the song to be "as Celine Dion-esque as possible" and lean into the cheesiness of it.

She also said that she was "nervous," but it was less nerve-wracking than expected because she was able to pre-record the track and then lip-sync while filming.

Early in season two, Kimiko was reunited with her brother, Kenji (Abraham Lim), and used sign language to respond to him.

During episode three, Frenchie (Tomer Capon) even told Kenji that the way he and his sister communicate was unlike any sign language he'd ever seen. That's because it was created specifically for the show.

The only way to top season one's memorable scene in which The Deep's (Chace Crawford) attempt at freeing a dolphin went horribly (and comically) wrong was to literally go bigger during season two — and they certainly didn't hold back.

Episode three featured a scene where Billy Butcher (Karl Urban) commandeered a speedboat named My Big Wet Dream and crashed it into a whale named Lucy. Naturally, the incident was distressing for The Deep, who's fond of ocean life thanks to his special abilities.

The scene was filmed in Lake Ontario and took a whole week to film, per Entertainment Weekly. The final product that fans saw was the result of CGI, VFX, and practical effects.

According to EW, it took five months to create Lucy the whale, who was made from silicone and Styrofoam.

There was also a "hidden backdoor" added to the fake whale so the crew could get a camera inside to film the actors' reactions when they found themselves amidst whale guts.

To make it look like The Deep popped out of the water on Lucy's back, the "Gossip Girl" alum got on a structure that somewhat resembled a mechanical bull and was covered in fake whale skin.

VFX supervisor Stephan Fleet also spoke to Entertainment Weekly about the minute details of the fake whale, like the pulsating organs.

"If you watch the scenes closely with Hughie inside the whale, you're gonna see this little thing pulsing behind him," Fleet said. "That's VFX. But we slowed it down and there's little blood squirts coming out of it. So much of what we do [on this show] is the timing of blood squirts."

"This season has given Jack Quaid a life-long fear of boats," Urban said during an interview with Entertainment Tonight.

The "Star Trek" alum said that they were "going fast" and "jumping waves" for real while filming. According to Urban, Quaid's safety word if he felt unsafe was "Karl." The only problem was that Urban couldn't hear his costar because there was a helicopter above that was used for filming the sequence.

"I thought he was just seasick or something but no, he was actually in mortal fear of his very life," Urban said, describing Quaid's face as "white as a sheet" when he looked over at him after one take.

In an interview with Collider, Laz Alonso (Mother's Milk) said that they were covered in artificial blood for 14 days. According to the actor, the process to get the fake blood applied to them took two hours, plus they were constantly retouched between the filming of scenes.

Quaid seemed to get the worst of it, telling Fault magazine that he "couldn't touch anything and flies and bees were particularly attracted to me."

"In season one, if I were splattered with blood, there'd be a time cut, so I'd move on the next scene right away," he said. "This season I get covered in blood, but we stay with my character, which means filming the scene involved weeks of me coming into work and getting blood applied all over."

Meanwhile, VFX supervisor Fleet told Entertainment Weekly described the interior whale scene, which showed Hughie drenched in blood, as "pretty miserable" because it was 100 degrees and the actor had to sit for three hours to film.

"It's so tight and it's so little," the actress told Entertainment Tonight, explaining that her microphone makes the whole process even more challenging.

"I'm like, wired up and the process of taking it on and putting it off — it's left me in positions where, let's just say, I've gone back to set and there have been articles of my costume that are a little wet," she said. "It happens."
