All I remember was this scene where a fat woman was laying down with some new tech gear that was trending apparently. She would put it around her head or something and it fried her brains and killed her. She wasn't an important character though. I think it might have been about a murderer? Who was using his new technology he was selling to tons of people and killing them.

I don't know how else to explain but it's really bothering me, if someone could help me with the name of this movie that would be awesome!

Probably not but sounds a little like Halloween II season of the witch. Sorry if it's not, just reminded me of it.

Maybe 'Brainstorm' with Christopher Walken

Fat woman fried was Ellen Burstyn
