The CW has moved "The Flash" from backdoor pilot status on "Arrow" to a standalone pilot.

According to Deadline, the CW has changed its initial plans for "The Flash." While Barry Allen will still be introduced in episodes eight and nine of "Arrow," the network has opted to produce a standalone pilot instead of using episode 20 of "Arrow" as a backdoor pilot for the series as originally planned. The decision was reportedly made after positive advance feedback from actor Grant Gustin's introduction as Barry Allen during episodes eight and nine. The new plans for episode 20 of "Arrow" -- and whether it will involve The Flash at all -- are currently unknown.

While the pilot is now standalone, the creative team will stay the same with Greg Berlanti, Andrew Kreisberg and DC Comics Chief Creative Officer Geoff Johns slated to write and "Arrow" pilot director David Nutter attached to direct.

"I think it is a little bit unique. I don't think we planned it," "Arrow" executive producer Marc Guggenheim told CBR in August, after the initial announcement of "The Flash" series. "But at the same time, quite frankly, we didn't plan to expand the DC Universe so much in the first season of 'Arrow.' For example, Greg [Berlanti], Andrew [Kreisberg] and myself never said 'In the first season of this show, we're going to introduce the Huntress and Deathstroke.' We really didn't have that plan. We were hoping to one day get to those characters, but we never thought it'd happen as quickly as it did."

Grant Gustin will appear as Barry Allen on "Arrow" for "The Scientist" (December 4) and "Three Ghosts" (December 11).
