This should, happen: Kevin Smith, Uber-geek an media maker, is saying that DC may allow the movie superhero characters (like Superman, Batman, Wonder Woman) interact with the TV DC Superheroes (like Arrow, Flash, Supergirl).
This needs to happen! In my humble, but correct opinion, DC has largely flubbed their movies, while hitting home runs with their television shows. Marvel has crushed DC in the theaters (Nolan’s Batman flicks notwithstanding), and, with the Netflix shows like Daredevil, is threatening to take over TV as well. DC needs to create a shared movie AND TV universe where there is ONE actor playing the Flash, not two, and we can see Supergirl really interacting with her cousin (i.e. the same guy we see duking it out with Batman in the movies).
