"This is heavy, Doc." (You better hold tight until the end to know what Marty is talking about...). In this episode of On Location, Curtis and crew travel around Southern California to hunt down the filming locations that made a 1985 science-fiction classic - Back to the Future! Buckle up and join us on our journey. Stay tuned until the end because we take the DeLorean Time Machine back to the original location (Puente Hills Mall - City of Industry, CA) where time travel first happened … and make it happen again more than 30 years later. Back to the Future Filming Locations ... not where, but when? Enjoy :)
