I watched this movie only once from the late 80’s or early 90’s. I saw it on tv. It’s in English / color. All I remember is there is a robot who is made to look exactly like a high school boy and he is sent to school to collect information or something. There is a scene where he is invited to a new friends house but starts to run out of batteries and needs to go into the bathroom to charge himself. The main actor/robot sorta reminds of of Michael J Fox but it probably wasn’t him. Please help me!!
