Despite a much ballyhooed report that the CW was in contact with WB's studio about a potential crossover, DC's chief creative officer Geoff Johns told reporters that DC/WB planned to keep television shows such as Arrow and Flash separate from the universe being built in Man of Steel and Batman v Superman: Dawn of Justice. "It's a separate universe than film so that the filmmakers can tell the story that's best for film," Johns told the Television Critics Association yesterday during a presentation about CW's DC shows. "While we explore something different in a different corner of the DC universe."
"We will not be integrating the film and television universes," Johns added.
This should settle what's been one of the bigger debates amongst Arrow (and Flash) fans (besides whether Oliver should end up with Felicity or not). Many fans of the shows have wanted to see the wanton destruction of Metropolis referenced in some way, or see actors Stephen Amell and Grant Gustin reprise their roles as Oliver Queen and Barry Allen in a rumored Justice League movie. However, others (like myself) were worried that the showrunners would be hampered by sharing continuity with a larger DC cinematic universe, especially seeing how Marvel's Agents of SHIELD performed in a similar situation.
That doesn't mean there won't be any crossovers in Arrow and The Flash's future. The CW confirmed that both shows' eighth episodes this season would be a two part crossover pitting Oliver and Barry against some sort of shared threat. Producers also confirmed that Felicity would be making an appearance in The Flash's fourth episode, the same episode that will introduce Wentworth Miller's Captain Cold.
The new season of Arrow and The Flash's first season begin this October.
