REALLY REALLY, YOU GUYS.
CBR has the details. There have been some conflicting reports regarding which Blue Beetle they'll actually be using. CBR seems to think it's Jaime, while
this report suggests it will be Ted.
It would make sense for them to use Ted, given Arrow was forced to scrap using him in Season Three and replace him with Ray Palmer, stating that "DC had other plans for Ted."
Bear in mind, of course, that the film is only in development. It could be a long time before this project hits theaters, if ever. It took over a decade for Mad Max: Fury Road to get made, after all.
Still. BLUE AND GOLD GOOFY BUDDY COP MOVIE. NOT A DREAM! NOT A HOAX! NOT AN IMAGINARY STORY!
