<human>:  I have a question about the movie Back to the Future (film). Where did the DeLorean time machine come from?
<bot>: The DeLorean time machine was built by Dr. Emmett Brown, who was a professor of physics at the University of California, Los Angeles. He invented the time machine in the movie, and he also invented the flux capacitor, which is the device that allows the time machine to travel through time.
