"The Flash" will race back onto TV sets on Tuesday, October 4, and the season premiere of the CW superhero series will see the debut of a new timeline. But as the series progresses, there's one specific event "Flash" lead Grant Gustin would like to see occur offscreen; he wants to see Joss Whedon direct an episode.

While speaking with the press at Comic-Con International in San Diego, Gustin fielded a question about other directors he'd like to see direct an episode of "The Flash." After all, season two saw fan favorite director Kevin Smith take over for an episode. "Yeah actually," said Gustin, with a director already on his mind. "I met Joss Whedon last night. Yeah, that'd be really cool. He was a really nice guy and he loves the show. He's seen every episode of the show."

Whedon most recently directed the two Avengers films, 2012's "Marvel's the Avengers" and 2015's "Avengers: Age of Ultron." And he's definitely no stranger to directing television shows; he directed dozens of episodes of his series "Buffy the Vampire Slayer," "Angel," "Firefly" and "Dollhouse." He's also directed episodes of "The Office," "Glee" and "Marvel's Agents of S.H.I.E.L.D."

And Kevin Smith, whose involvement behind the camera in season two of "The Flash" inspired the question, will also return to direct an episode in the third season. Smith is slated to helm episode seven of season three.

"The Flash" returns to the CW on Tuesday, October 4.
