@itvnews: Voice actor Peter Cullen, best known as Optimus Prime in the Transformers franchise, has died at the age of 85. He voiced the Autobot leader for nearly four decades, from the 1984 animated series through to the recent live-action films. Cullen based the character on his older brother Larry, a US Marine who served in Vietnam and who he called his hero. His family have asked people to remember him by his own words: "be strong enough to be gentle." #Transformers #OptimusPrime #PeterCullen #News
