Screenwriting Lessons from The End of Oak Street

“It was an unexpected, bonkers script to read,” Ewan McGregor said in a SciFiNow interview.

The star of The End of Oak Street was pulled into the story for two reasons: it showed that the idyllic life of a 1980s suburban family was not as cheerful as it seemed and then there were dinosaurs.

The film feels familiar and pushes nostalgia of simpler times before the internet, smartphones and information overload while creating something completely original and fresh. Writer/director David Robert Mitchell showed that he can write something completely new yet mainstream.

This article is going to take a look at the benefits of writing high concept, how to write a science fiction movie in today’s world, why you should never be afraid to be ambitious and some other screenwriting lessons from The End of Oak Street.

Original Scripts Wanted

When it seems like the biggest movies are comic book films, sequels and remakes, it’s hard to think that an original script can slip through, generate buzz and get backed by a major studio. That’s simply not true – it’s just not easy.

If you go back 46 years to 1980, some of the biggest box office hits weren’t original:

There is always an appetite for familiarity because moviegoers would rather pay money to see a story they’ve heard of. That’s why studios (and anyone investing their money) are more willing to back something that has intellectual property behind it.

It doesn’t mean original screenplays are chucked to the side. Producers are always looking for the next hot property and readers want to discover a screenwriter with a unique and fresh take. And don’t forget, producers need writers – so, while they may not end up making your screenplay, your script sample might give you the opportunity to write the next big blockbuster.

Is there a type of story you can write that will appeal to a producer? Yes. It’s called high concept.

What is High Concept?

High concept is a simple idea that can be explained in a sentence, maybe two, and immediately conveys the genre, premise and unique hook of the movie.

The End of Oak Street: What if dinosaurs appeared in a quiet suburban neighborhood and the people couldn’t escape?

That’s a concept anyone can understand and one that intrigues moviegoers. But not every high concept movie requires a big spectacle like dinosaurs, aliens or giant explosions.

Other high concept examples:

• Liar, Liar: A lawyer who makes a living bending the truth can’t tell a lie for 24 hours

• Speed: A terrorist places a bomb on a city bus where if it drops below 50 mph it explodes

• Weapons: A classroom of kids all disappear one night except one child

• M3GAN: An AI robot takes its programming of protecting a young girl to deadly lengths

• Cocaine Bear: A bear consumes a massive amount of cocaine and goes on a rampage

The key to a high concept idea is that it’s easy to communicate while leaving room for story development. It’s not about coming up with the biggest idea possible, but finding an idea that makes someone stop and say, “I want to see that.”

Not every writer wants to write high concept. That’s okay. Maybe your story is complicated and requires a little more information to intrigue an audience. Regardless, it’s good practice to try to tell the concept of your story in as few words as possible.

How to Overcome the Challenges of Writing Sci-Fi in 2026

Technology is advancing at such a rapid pace. What feels futuristic now might seem like old news when your movie comes out. How can screenwriters keep up in a world of artificial intelligence, virtual reality and handheld and wearable tech?

Don’t worry. You don’t have to predict the next technological breakthrough. In The End of Oak Street, Mitchell went backwards. The film takes place in 1982 when the internet, smartphones and social media didn’t exist. Denise (Anne Hathaway) types on a typewriter and researches at a library instead of Google. Communication is sparse because no one can go on social media to see what’s happening in their neighborhood.

Science fiction doesn’t have to be about technology, but about how characters react to what’s around them or use it as part of the story. Recently, the sci-fi show Alien: Earth had the characters using some of the same, older-looking technology from the original Alien film – which looks considerably outdated to modern viewers. It didn’t matter because it was the story that viewers tuned in for.

Screenwriters should focus on the people’s experience in the story – that’s what the audience connects to. The dinosaurs might get them into the theater, but it’s the characters that make it memorable; just like the alien will get people to watch Alien: Earth, but the characters and story keep them tuning in.

Create a Human Problem Before a Genre Problem

The dinosaurs, the humans’ desire to return to their normal world and surviving in a world without water or electricity might be the hook of The End of Oak Street, but that’s not the only problem. Before the creatures arrive, Denise and Greg (Ewan McGregor) are already dealing with their own personal crises: their marriage is falling apart and the kids are taking notice.

Characters must deal with something beyond the external conflict. The human problem, or the internal conflict, can manifest itself throughout the crisis. For example, when boarding up their house to avoid the dinosaur threat, Denise says to Greg that she smells whiskey on his breath. We saw him drink prior to the event so we understand this is something he’s hiding from his wife and now he’s using it to calm his nerves. What the audience sees is another relatable relationship conflict within the marriage as they are going through the act of protecting their home.

The family struggles make it harder to stay together in a catastrophe that requires teamwork. This is used all the time in Marvel movies by driving the superheroes apart for personal reasons when they must stick together in order to defeat the enemy.

Mitchell establishes those family dynamics early and provides the characters with something personal to fight for while also giving us a reason to care about these people before the larger threat takes over.

No Actor Wants to Say “Hello”

The last thing an actor reading a script wants to see when their character is introduced is them saying, “Hello.” Unless the action that follows involves them punching someone in the face.

When you watch some of your favorite movies, rarely is a character’s introduction boring. They enter rooms with gravitas, trip over themselves, land in that three-point superhero pose or say something memorable.

They may not even have a line:

• Indiana Jones doesn’t say a word at the beginning of Raiders of the Lost Ark, but think about how he’s introduced to audiences.

• Jack Sparrow in Pirates of the Caribbean steps off the mast of his sinking ship onto a dock with all the confidence in the world.

• In Silence of the Lambs, after walking down a creepy, dark hallway with psychotic prisoners, Clarice finds Hannibal Lecter standing straight with a slight smile.

• In Willy’s Wonderland, Nicolas Cage plays a character who remains silent the entire film.

Actors generally like a challenge. To create the roles that actors want to play, most want to stretch their skills or (seriously) they want cool dialogue. It’s why people love working with Aaron Sorkin, who is known for his fast, clever dialogue, or Quentin Tarantino.

In his SciFiNow interview, McGregor said of the screenplay, “…what I liked about it was that there was something not quite right about the couple, some unhappiness in their marriage amongst this 1980s perfect life, these Americana vibes. That was intriguing. And then the dinosaurs come in, and I couldn’t believe what was happening as I was reading the script.”

The attraction wasn’t just running from dinosaurs but doing that while trying to hide from his troubled marriage. That gives the actors conflict, emotion and plenty of opportunities to reveal different sides of their characters.

When developing your own screenplay, ask yourself what makes each major role irresistible to an actor. Here are some clues you’re on the right track:

• Strong introduction

• They make meaningful choices

• Have real strengths and weaknesses

• Have moments of vulnerability

• Opportunities to surprise the audience

• They’re not just there to move the plot forward

Be Ambitious (but Keep Budget in Mind)

Screenwriters shouldn’t avoid big ideas!

It’s important as a writer to be ambitious in the story you want to tell and not sacrifice the big moments because they might turn a producer off.

However, screenwriters must be smart about where they spend their spectacle and make those expensive moments worth it.

The End of Oak Street is not a small movie on the page; you have CGI dinosaurs roaming a suburban neighborhood and houses being destroyed. But it’s not constant. The first act builds to the moment with zero spectacle. After the cosmic event, there are scenes that take place in the family home where there are no dinosaurs, just story. But the action set pieces are grand and great, certainly expensive and make the audience lean forward in anticipation. They work because Mitchell builds toward those moments rather than filling every page with dinosaurs chasing people down.

At the same time, look for ways to create spectacle through suspense and imagination. Sometimes what the audience doesn’t see can be just as effective as what it does. Think about Jaws and how the shark is rarely seen but always present, building terror without popping out of the water.

Sometimes a strange sound outside the house, an unexplained shadow or characters reacting to something terrifying works without that expensive visual-effects shot.

Remember, you should never make your screenplay smaller because you’re worried about the budget. Be ambitious about the story, then be intelligent about how you tell it.

You Don’t Always Need Dinosaurs

The End of Oak Street proves that an original screenplay can still feel familiar, accessible and completely unexpected. And it’s not the only film to do it this year. Movies like Obsession, Backrooms and The Drama are all original stories that made big splashes in 2026 and were made with a relatively modest budget – Obsession, made for $750,000, has raked in over $495 million at the box office. The Drama is a dark dramedy starring two of the biggest actors in Hollywood.

They’re not all high concept or big spectacle but they have relatable characters, personal conflict and a mystery that keeps the audience asking questions. All these movies take something familiar and show the moviegoing public something they’ve never quite seen before.
