Those ear-splitting impact tremors you hear outside your window aren't just noise from the nightly commute or a local construction site, they're the sound of Michael Bay's Transformers: The Last Knight bounding onto Blu-ray and DVD.

With the home video campaign in full force, SYFY WIRE cornered the distinguished vocal actors for Optimus Prime and Megatron, Peter Cullen and Frank Welker, and discussed their three decades of on-screen conflict. The booming voices of two of the most recognizable robots in disguise have shared a turbulent relationship in their sci-fi films but are great friends in real life.

From the Transformers Generation 1 series in 1984 to the recent Transformers: The Last Knight, this mellifluous pair have been clashing for 33 years in the metallic torsos of their respective alien robots with every expressive line and dominating exaltation.

Listen in to their reminiscences of working together over the years and learn what makes this legendary rivalry so rare.
