While fans remain concerned about the future of the movie, voice-over artist and actor Peter Cullen -- the original voice of Optimus Prime -- has revealed how he worries about Transformers becoming darker with each sequel. Cullen shared his concerns over the image of the Transformers at the SacAnime2015 conference, Air Herald reported.
Despite the uncertainty of some cast members returning when news first hit about TF4, Peter Cullen will definitely be reprising his role as the voice of Optimus Prime. We also now know that the film will not be a total reboot, and will not jump ahead years from where the plot ended in the last one.
