It was just reveled that the Autobot Hot Rod will be in the next live action Transformers movie "The Last Knight".  So just like the fans did with Peter Cullen for the 2007 movie, I think it would be awesome if Judd Nelson, the voice of Hot Rod in the G1 Transformers Animated movie from 1986, got the chance to reprise his character in the new movie by Michael Bay.
Hot Rod/Rodimus Prime is as iconic to the Transformers franchise as Optimus Prime is, and just like Optimus Prime, I feel that Judd Nelson would bring back the nostalgia of the G1 movie.
