The CW have released a slightly-reworked pilot for Arrow that includes a couple of seconds of footage from (and a different logo for) The Flash, the network's upcoming Arrow spinoff.

The Flash star Grant Gustin posted the trailer to Twitter (see below), telling fans to watch Arrow's finale on Wednesday for a sneak peek at The Flash -- a sentiment the trailer itself reiterates. Presumably (as predicted), the 75 seconds added to Arrow will accommodate the first look, be it a trailer, a post-credits scene or some variation on the two.

The brief look at The Flash doesn't actually show Barry Allen himself -- just Oliver Queen as Arrow, in a field in the middle of nowhere, seeing the ground being disturbed, followed by a blur of motion that leads to the logo. Could this mean that the pilot for The Flash features a cameo (or more) by Arrow himself? We'll almost certainly find out more over the next couple of days -- and this likely cements the idea that Arrow star Stephen Amell's teased Facebook reveal will be Flash-related.
