Greg Berlanti, executive producer of “Arrow” and the “Flash” pilot, explains the differences between the two shows in an interview with Digital Spy. With the sci-fi feel, “The Flash” has the option of bringing in more characters with super powers — whereas “Arrow” mostly keeps to a heightened reality.
“Barry [in ‘The Flash’] is different from Oliver,” Berlanti explains. “He’s a man of science and has more of a sci-fi bent, whereas ‘Arrow’ has a bit more of a crime bent.”
The differences in themes will also reflect the worldviews of Oliver and Barry. “Barry has an effervescence and a lightness, but there’s still a dark well beneath that,” Berlanti says of Barry Allen. Oliver queen, in contrast, is a hopeful optimist in his belief that Starling City can be saved.
Finally, there is the basic fact that “The Flash” begins with the explosion of a particle collider that imbues Barry with incredible speed. That same accident could create a host of other powers to both help and hurt Barry.
“Arrow” airs Wednesdays at 8 p.m. on The CW. “The Flash” pilot is in production and, if it’s picked up to series, would air during the 2014-15 season.
