Back to the Future

Factual error: Marty McFly goes back in time to visit his mum-to-be and finds her watching an episode of The Honeymooners. The date is given as November 5, 1955 and yet the episode of the show - The Man From Space - was not screened until December 31, 1955. (00:44:15)

Factual error: When Biff is chasing Marty (on the 'skateboard') around the Town Square, you can see curb cuts at the corners. Aside from a trial program in Kalamazoo, Michigan in the '40s, they didn't spread further until well after 1955. (01:05:58)

Factual error: The electric guitar Marty plays at the "Enchantment Under the Sea Dance" is a Gibson ES345. This guitar model debuted between 1957 and 1958 yet he's supposedly playing it in 1955. It would have been more accurate to have him using a Fender Telecaster (1950) or Stratocaster (1954) or a Gibson Les Paul (1952). (01:23:50)

Factual error: When Marty hits his head on the DeLorean's steering wheel, the car's horn honks. This is inaccurate to the design of real-world DeLoreans, as a DMC-12's horn button is actually located at the end of the turn signal lever rather than in the steering wheel. (01:39:27)

Suggested correction: You can't see his left hand and he could have accidentally pushed it when he hit his head. Or Dr. Bown customized the steering wheel so the horn is in it, like he customized the entire interior of the car.

Factual error: When Marty walks out of Lorraine's house, next to the front door is a light dimmer switch. Dimmer switches weren't invented until the late 1950s to early 1960s.

Factual error: In the skateboard chase scene, after the crash, a crowd gathers. In this crowd there is a kid dressed in a Cub Scout uniform. He has a red/white town strip patch on his arm. In 1955 the Cub Scout town strip patches were blue with gold lettering.

Factual error: Video/audio output on the JVC camcorder (if it had any at all) would not be compatible with 1955 TV. if available the camcorder output would be composite, component or COAX - all would need some sort of adapter for the audio/video to work on the TV. COAX would be the simplest, but they would need to invent the 75 ohm to 300 ohm adapter.

Continuity mistake: When Marty chases after Biff on the borrowed 'skateboard', Marty is wearing a dark grey belt and a red/blue print shirt under his red/beige jacket. However, when Marty is hanging on to the front of Biff's car as they turn a corner (and in another shot), Marty (stunt double) is wearing a light brown belt and solid tan shirt. (01:07:00)

Trivia: In the battle of the bands scene, when Marty introduces The Pinheads, Huey Lewis, who provided "The Power of Love" for the film's soundtrack, plays the second judge from the left, and is the one who eventually says, "You're just too darn loud." (00:07:40)

Question: What does the saying "Why don't you make like a tree, and get out of here", mean?

Answer: It's a way of saying "scram" or "get lost." But Biff is so dim, he doesn't realize he's saying it wrong; the expression is "make like a tree and leaf", with the joke being that "leaf" is meant to sound like "leave."
