I need your help to identify a movie I didn't see, but I saw the preview. A group of men in suits were in a boardroom [View all]

demonstrating a robot, which I think was a security robot.

One man told the robot that another man was the bad guy, so the robot went after the second man. This was just a demo, so they tried to call the robot off, but something fubared and the robot didn't stop.

This was a while back, maybe 20 years ago.

Anybody know this movie?
