The Imperious Leader vs. The Supreme Leader

...just a quick mention...!

Is it just me, or is The Supreme Leader from Star Wars: The Force Awakens (2015) **very similar** to The Imperious Leader from Battlestar Galactica (1978 - 79)?  Both of these evil characters (with **remarkably** similar names!) are mostly obscured by shadows and reside in a darkened chamber.  Both characters are depicted atop gigantic thrones / pedestals and "lord it over" their visitors.  Below are photos of both characters:
