Transcendence
In this Johnny Depp movie from 2014 that literally nobody knows about, Depp plays an AI building scientist who gets shot by an anti-technology terrorist organization and decides to upload his brain to the quantum computer he has created since his body isn’t going to make it. He manages to create lots of ground breaking, world changing, technological advances in this human brain/supercomputer hybrid state but people start getting uncomfortable once he gains the ability to hack into and control people’s minds.
