3. STANLEY KUBRICK GETS A NOD
The sticker on the amp Marty plugs into in Doc’s garage says “CRM 114,” which is a nod to director Stanley Kubrick. In Kubrick's films, the CRM-114 Discriminator is a fictional radio device in Dr. Strangelove. It’s also the homophone "Serum 114," the experimental drug given to Alex (Malcolm McDowell) in A Clockwork Orange; and it’s the serial number of the Jupiter explorer in 2001: A Space Odyssey.
4. MARTY’S INTO SOVIET ART.
The black and red badge Marty wears on his denim jacket says “Art in Revolution,” which was a Soviet art and design exhibition that was held at London’s Hayward Gallery from February to April in 1971.
5. ROBERT ZEMECKIS GAVE A NOD TO ONE OF HIS OTHER MOVIES.
As Marty skitches on the fender of a Jeep in the town square, a sign reads “Used Cars,” which is the name of a 1980 movie directed by Zemeckis and written by Zemeckis and Gale.
The newscaster seen on the TV in the opening sequence is actress Deborah Harmon, who appeared in Used Cars.
6. MAYOR RED THOMAS FELL ON HARD TIMES.
When Marty sees the tramp on the bench in 1985 he shouts out the name “Red,” which could indicate this character is Red Thomas, the mayor of Hill Valley in 1955.
The photo of Thomas on his 1955 reelection campaign is actually Back to the Future’s set decorator, Hal Gausman.
7. THE GUY WHO THINKS MARTY IS "TOO DARN LOUD" PROBABLY LOOKS FAMILIAR.
The school administrator with the megaphone who chides Marty’s band, The Pinheads, for being too loud is singer Huey Lewis in his first acting role. The scene had an added irony as Lewis made The Pinheads stop playing his own song, “Power of Love,” which appeared on the Back to the Future soundtrack.
Marty also has a poster for the Huey Lewis & the News album “Sports” in his bedroom, and when Marty wakes up after getting back to the future in the improved 1985, Lewis’s soundtrack song “Back in Time” plays on his alarm clock radio.
8. SOME CREW MEMBERS GOT BACKGROUND SHOUT-OUTS.
When Marty and Jennifer walk across the town square parking lot after his failed audition, a license plate on a green car in the background reads 'FOR MARY,' which is a nod to Mary Radford, the PA to the film’s second unit director Frank Marshall.
Another reference to one of the crew can be seen on a poster on the wall of the high school in 1955, which reads 'Ron Woodward for Senior Class President.' Ronald T. Woodward was the film’s key grip, and had previously worked with Zemeckis on Romancing the Stone.
