Superman Unbound has been adapted from Geoff Johns and Gary Frank's Action Comics arc, Brainiac. The premiere will be at Wondercon in Anaheim this spring, and then we'll see it roll out on DVD and Blu-ray.
I still find the stylised voice performances of Warner Bros. animated films rather off putting. Is there any reason this shouldn't be played with at least the modest degree of naturalism heard in a Disney-Pixar toon? Or even live action?
