The Flash/Supergirl crossover "Worlds Finest" is the must watch event for DC TV Fans, and here's why. This CW/CBS shared story will ignite a fire that DC execs cannot ignore. DC TV characters deserve to be part of the Cinematic universe as well. The television stories involving The Flash, Green Arrow, Supergirl, and now Martian Manhunter are capturing the audiences and making a strong argument against recasting these icons for the cinematic universe.
Although the decision has been made in regards to separating the two universes, fans will take to the forums making the case for Steven Amell, Grant Gustin, and Melissa Benoist to make appearances in some of the future JLA movies. Of course, talk about Crisis on Infinite Earths will only get hotter as eventually DC Execs will have to confront the obvious-the fans REALLY want this to happen. It's unlikely, but hey-anything can happen.
Watch the “Worlds Finest” episode of Supergirl when The Flash suddenly appears from an alternate universe. Barry Allen agrees to help Kara battle a few bad girls in exchange for help finding a way back home. SUPERGIRL "WORLDS FINEST" airs 3/28/2016 on CBS.
