Pretty sure it’s from a movie but not certain

I can only remember one scene, a man is watching a video recording and sees like a blue man made out of electricity and gets startled and jumps back. Thanks

Maybe the movie Watchmen (2009)? The character of Dr. Manhattan?

No it was more of a corporeal figure and an older movie. Thanks though

Ok, lets try some electrocuted serial killers!

Or

This one was also known as House 3 in the UK.

Lawnmower Man? it has sequels too
