The First Arrow/The Flash Crossover Episode Is Officially In the Works

The eighth episodes of The CW's Arrow and The Flash will cross over the DC Comics adaptations for a two-hour, two-night event, and the process is now officially underway.

That's according to the tweet below (and the image above) from the Twitter account for The Flash's writers.

Leading into the crossover events, Arrow will feature a two-episode arc (episodes 7 and 8) featuring classic Flash villain Captain Boomerang.
