Kevin Smith directed tonight’s Season 3, episode 7 of “The Flash,” and although it’s actually the second “Flash” episode he's helmed, he admitted that he was “terrified” doing it.

In a recent interview with Variety, Smith revealed that he started to worry about his second directorial gig on the CW series when he found out that the episode he was going to shoot was not written by Zach Stentz.

“I made sure I had my crew again — the folks I shot with the first time — and then Zach Stentz wrote the episode ‘Runaway Dinosaur’ so I said, ‘Zach, you’ve got to write my episode,’” Smith shared with the news outlet. “Originally I was supposed to do episode 5, and Zach did write that episode, but I was doing ‘Yoga Hosers’ press and had to miss it. Instead of doing [episode] 6, I waited for that odd-numbered crew and did [episode] 7, but I didn’t get to do Zach’s script so I was terrified, thinking, ‘Oh God, Zach was the magic feather and without him this is going to blow.’ So yeah, I was very paranoid.”

Despite Smith’s worries, the episode, titled “Killer Frost,” turned out to be great, and the cast were just glad that he returned to direct another episode.

“Kevin is so passionate and so knowledgeable. It’s his enthusiasm that really permeates the set,” Danielle Panabaker, who plays Caitlin on the series, told TVLine of Smith. “He has a lot of trust in the actors, that we’ve done our homework and are prepared. One thing that he in particular has is an incredible mastery of storytelling and this ability to finesse the script to help tell the story the best way possible. He also knows what he’s going to use, what he is going to cut to, so he doesn’t waste time…. He’s specific and clear about what he wants.”

Panabaker’s co-star Tom Cavanagh also recently gushed over Smith. “He’s one of the most gregarious, generous and accomplished people I’ve ever met in the entertainment world,” Cavanagh told Variety last month when asked about his experience working with Smith. “He’s so engaging and genuine, and his energy lifts everything in whatever job he happens to be doing at the moment. He’s one of a kind, and we’re so fortunate to have aligned ourselves with him.”
