There has been a change in the CW‘s plans for The Flash. Originally, the character, played by Grant Gustin, was supposed to appear in three episodes of Arrow this season — No. 8, No. 9 and No. 20, the last one serving as a backdoor pilot directed by David Nutter. Episodes 8 and 9, in which the superhero is introduced only as his alter ego Barry Allen, have already been shot. But now the CW has opted to film a traditional stand-alone Flash pilot instead of doing a backdoor pilot as Arrow‘s Episode 20. With Episodes 8 and 9 serving as an origin story, the plan was for The Flash character to make his debut — red costume and all — in Arrow‘s Episode 20. He will now do it in the pilot. The creative team remains the same, with Arrow co-creators Greg Berlanti and Andrew Kreisberg and series scribe Geoff Johns writing the pilot and Nutter, who helmed the pilot for Arrow, directing. Berlanti, Kreisberg and Nutter executive produce, with Melissa Kellner Berman co-executive producing.
