We all knew that the CW’s Arrow and The Flash were going to have a crossover and now we know the title of the episode. The episode started filming yesterday, September 29, 2014. The title of the 2 hour long crossover episode is “The Brave and the Bold.”  This title has been used a few times in the DC universe. It’s best known as Batman’s long running comic book series and the three-season animated series of the same name, Batman: The Brave and the Bold.
This episode will be directed by Jesse Warn, who also directed last season’s “The Man Under the Hood.” Warn will also direct The Flash‘s 3rd episode, “Things You Can’t Outrun.” The first part of the crossover will air as the eighth episode of The Flash with the title “Flash vs Arrow.”
