When a solo show never came to fruition, The Flash was introduced to Smallville. To date, the show is the only adaptation of Bart Allen, the fourth Flash in the comics also known as Impulse. Bart was played by Kyle Gallner across four episodes, from the fourth season to the tenth. The character was presented as part of Clark Kent’s band of teenage superheroes who form a prototype version of the Justice League.
David S. Goyer’s The Flash Movie (2004)
In 2004, it was announced that prolific screenwriter David S. Goyer (later to write The Dark Knight trilogy) was penning the script for a Flash movie. It would have drawn from Sam Raimi’s Spider-Man movies for influence on tone and style. Goyer approached Ryan Reynolds (eventual star of both Green Lantern and Deadpool) to lead the movie.
DC Animated Movies (2008 -)
The Flash has appeared in a number of DC’s ongoing series of straight-to-DVD animated movies. The first was Justice League: The New Frontier in 2008, which starred Neil Patrick Harris as the Scarlet Speedster. Future movies have featured the voices talents of James Arnold Taylor, Justin Chambers and Christopher Gorham. Michael Rosenbaum and Charlie Schlatter have also reprised their roles in one movie apiece.
