We all remember the hoverboard. We remember the self-lacing Nikes and that weird double-tie fashion choice that, thankfully, never actually became a thing in the real 2015. But when people talk about Marty Back to the Future 2, they usually focus on the gadgets or the confusing timeline math. They treat Marty McFly like a static chess piece being moved around a board by Doc Brown.
That's a mistake.
Honestly, the sequel is where Marty actually grows up, and it happens through a character flaw that wasn't even in the first movie. You've probably noticed it: the "chicken" thing. In the original 1985 film, Marty is a cool, somewhat frustrated kid who just wants to play rock and roll. He isn't particularly thin-skinned. But by the time we get to the second installment, he’s developed this hair-trigger temper. If anyone calls him yellow or a chicken, he loses his mind.
Why the "Chicken" Trait Changed Everything
It feels like a retcon because, well, it kind of is. Bob Gale and Robert Zemeckis needed a way to give Marty an internal conflict for the sequels. They gave him the "McFly streak"—an insecurity passed down from George McFly, but inverted. Where George was paralyzed by fear, Marty is paralyzed by the fear of being seen as fearful.
It's a subtle distinction.
Think about the scene in the Cafe 80's. Griff Tannen calls him a chicken, and Marty stops dead in his tracks. He knows he has to save his son. He knows time is of the essence. Yet, he can't walk away. This one specific personality trait is what drives the entire plot of the second and third movies. Without it, Marty wouldn't have stayed in 1955 long enough for the DeLorean to get struck by lightning. He would have just grabbed the almanac and left.
The Michael J. Fox Marathon
The production of this movie was a nightmare for Michael J. Fox. Seriously. He was still finishing the final season of Family Ties while shooting the sequels back-to-back. He’d work on the sitcom during the day and then show up to the Back to the Future set at 6:00 PM, working until sunrise.
You can actually see the exhaustion in his performance, and strangely, it works.
In Marty Back to the Future 2, Marty is constantly overwhelmed. He’s bouncing between a futuristic 2015, a dystopian "Hell Valley" 1985, and a rainy 1955. Fox had to play four different versions of the McFly family in this film alone:
- Teenage Marty: The one we know and love.
- Middle-aged Marty: The 47-year-old corporate "slacker" with the broken spirit.
- Marty Jr.: His wimpy, whiny son.
- Marlene McFly: His daughter (yes, that was Fox in a wig and dress).
The "VistaGlide" system allowed Fox to interact with himself on screen, which was mind-blowing in 1989. But for the actor, it meant filming the same dinner scene over and over, reacting to empty space, and switching costumes for hours.
The Hell Valley Mistake
Most fans focus on Biff stealing the almanac as the "big bad" moment. But look closer at Marty's choices. When he’s in the alternate 1985—the timeline where Biff is a billionaire mogul—Marty goes to his old house. He finds it occupied by a different family.

Instead of being cautious, he acts with typical teenage entitlement. He nearly gets shot because he hasn't realized that in this version of reality, he doesn't belong. This is the moment where the stakes shift. In the first movie, the threat was Marty fading away. In the second, the threat is the world becoming a literal graveyard.
It's dark. Way darker than the first one.
The fact that George McFly is dead in this timeline (because Crispin Glover didn't return for the sequel, leading to some clever recasting and use of old footage) adds a layer of genuine grief to Marty's journey. He isn't just trying to "fix" things anymore; he's trying to resurrect his father's life.
What Most People Get Wrong About the Ending
There’s a common complaint that Marty is "responsible" for Doc getting trapped in 1885. People say if he hadn't hesitated when Biff called him a chicken at the dance, they would have made it home.

Technically? Maybe.
But the real insight is that Marty's journey in Part 2 is about learning that you can't cheat your way to a better life. He bought the almanac to make easy money. Doc scolded him, saying the time machine wasn't for profit. By the end of the film, Marty has seen the logical conclusion of "easy money" in the form of Biff’s empire. He realizes that the shortcut leads to a dead end.
Key Takeaways for the Ultimate Fan
If you're rewatching the trilogy, pay attention to these specific details in the second film:
- The Shoes: The Nike Mag power laces were actually operated by several stagehands pulling wires through the floor. They weren't "real" tech, but they became so iconic that Nike eventually made a limited run for charity years later.
- The Western Hint: In the 2015 scene, Marty sees A Fistful of Dollars playing in Biff's hotel. He sees Clint Eastwood use a piece of metal as a bulletproof vest. He uses that exact trick in the third movie. The seeds are planted early.
- The Recasting: Elisabeth Shue replaced Claudia Wells as Jennifer. They actually reshot the entire ending of the first movie with Shue so they could use it as the opening of the second. If you watch them side-by-side, it's a "spot the difference" game for the ages.
To truly understand the Marty of the second film, you have to look past the hoverboard. You have to see the kid who is terrified of being a failure like the "original" 1985 George McFly. His aggression is a defense mechanism. It’s only when he lets go of that need to prove himself—specifically in the final moments of the third movie when he refuses to race Needles—that he truly "wins."

Go back and watch the scene where 2015 Marty gets fired. It’s a depressing look at what happens if Marty doesn't change. He’s a guy who let a single moment of pride ruin his hands and his music career. Part 2 is the warning; Part 3 is the cure.
Next time you see Marty McFly on screen, don't just look at the red vest. Look at the way he reacts when he's backed into a corner. That's where the real story is.
