So, is 'Click' really the only one?

Hello to all you STS members.
My wife just DVRed this and asked me if I wanted to see it. So, I looked it up and ... here I am. I haven't watched it yet, and am definately intrigued by all your comments.
When I read the plot summary, I thought it was a great premise and wondered if the story had been done in any other films. "Click" was the only one I came up with. So, my question is: what other films have this set-up?
Two of my faves are computers-take-over films; They are "Colossus: The Forbin Project" and "The Demon Seed". Do they count as a twonky-type movies?
Those are the closes I can think of; any others...?
