When designing the time machine, director Robert Zemeckis chose the DeLorean for its distinctive gull wing doors and futuristic look, which he hoped would make it more plausible that people in 1955 would mistake it for an alien spacecraft.

The buttoned-up judge with the megaphone is actually award-winning musician Huey Lewis, of Huey Lewis and the News, whose songs "The Power of Love" and "Back in Time" are featured on the movie's soundtrack. The song Marty's band plays for the audition is a remix of "The Power of Love" as well. Unfortunately, they are just "too darn loud."

Einstein is present at the Twin Pines Mall parking lot, where Doc Brown conducts his first time travel experiment, with Doc controlling the DeLorean via remote, Einstein sitting inside it, and Marty filming.

The flux capacitor requires 1.21 gigawatts of electrical power to operate, which is roughly equivalent to the power produced by 15 typical commercial airplane jet engines.

He obtains the plutonium from a group of Libyan terrorists by promising to build them a bomb with it.

After the Libyans shoot Doc, Marty is forced to flee in the DeLorean and finds himself transported to November 5, 1955, without any plutonium for a return trip.

He crashes into the farm of Old Man Peabody, who has a son named Sherman. This was in tribute to a segment in the The Bullwinkle Show (1959-1963), "Peabody's Improbable History", featuring the intelligent talking dog Mr. Peabody and his boy Sherman, who travel to different times in history using the W.A.B.A.C. Machine.

DOC BROWN: Ronald Reagan?!? The actor?!? Then who's vice-president? Jerry Lewis?!? I suppose Jane Wyman is the First Lady!

Doc Brown laments that there's no way to know when or where lightning will strike, but Marty shows him a flyer from the future that recounts a lightning strike at the town's courthouse that coming Saturday.

People are constantly mistaking Marty for a member of the Coast Guard because they think his orange "Class 5" down vest is a life jacket.
