He’s returning to The Flash for an episode titled ‘Killer Frost’, and will additionally lend his talents to an episode of Supergirl titled ‘Supergirl Lives’.
Previously, Smith directed an episode of The Flash late in season 2, titled ‘The Runaway Dinosaur’.
In addition to the planned crossovers, both The Flash and Supergirl will feature episodes directed by geek-favorite writer/director/podcaster Kevin Smith.
Although co-developed by The CW’s Arrowverse architect Greg Berlanti, Supergirl originally landed at CBS, where the show debuted its first season last fall.
