Melissa Benoist and Mehcad Brooks have nothing but praise for Kevin Smith, who recently finished directing the upcoming Season 2, episode 9 of “Supergirl.”

In an interview with Collider, Benoist said that Smith was “so supportive and encouraging” as a director. “We work crazy long hours, and the energy that he brings is only positive,” said the 28-year-old actress, who plays the titular role on the CW series.

“You guys saw how many rounds of applause there were [when Smith was directing],” Benoist told Collider and other news outlets who were invited to the show’s Vancouver set earlier this month. “That’s like a daily occurrence, all day, and I don’t know how you keep that up. He’s wonderful.”

Brooks said the same thing about Smith’s directing style. “He … brings this amazing energy to the set,” the 36-year-old actor said of the filmmaker, who rose to prominence for his 1994 comedy film “Clerks.” “He’s always applauding, laughing, clapping, yelling out things that are funny. He sort of makes the day go quicker.”

Brooks, who plays James Olsen on the series, also explained why Smith is considered as “everybody’s favorite.” “Kevin is an actor’s director. He’s a crew director. He’s a lighting director. He’s a camera director. He’s everything,” Brooks told Collider. “And he makes you understand that it doesn’t have to take eleventy billion hours to get the right thing, you know? And to make it look really good.”

The episode Smith directed is titled “Supergirl Lives,” which is a nod to the canceled “Superman Lives” movie that he wrote back in 1996.

The synopsis for the episode is yet to be released, but Smith teased on Instagram four weeks ago that the installment is “filled with deep-cuts characters” from some of his favorite stories in the comics. “It’s pure comic book and science fiction fantasy,” he wrote of the episode’s script.

In a more recent Instagram post, Smith commended the whole cast and crew of “Supergirl” for making a “fantastic” episode. “I know this not only because I was there watching when they did it, but also because I’ve already peeped some of the scenes our editor Barbara [Gerard] cut together,” he wrote on the social networking site, alongside a photo of the t-shirt he gave to all the cast and crew of the show. “This thank you t-shirt is the least I can do for the folks who made me look like I might be good at my job.”

According to Collider, “Supergirl” Season 2, episode 6 won’t air on The CW until January.
