Thirty-five years after Teenage Mutant Ninja Turtles II: The Secret of the Ooze first hit theaters, audiences are once again heading back to the big screen, this time for the film’s first-ever 4K theatrical presentation March 13th-19th.

Originally released in 1991, Teenage Mutant Ninja Turtles II, the sequel to 1990’s box office phenomenon, helped cement the Turtles as global pop icons. As the film returns to theaters nationwide through Fathom Entertainment, we had the rare opportunity to sit down with screenwriter Todd W. Langen, who wrote both of the first two live-action Turtle films.

At his core, Langen sees himself as a comedy writer first.

“I’m a comedy writer,” Langen says. “I approached both the first two TMNT movies as being COMEDIES, rather than action-adventure movies,” he says. “This allows their moments of drama – in contrast (including “action”) – to land with even greater impact.”

An early exchange in a basement conference room of Mirage Studios, and the sketch that came out of it, captures the energy of those early discussions.

Starting with the Source

When asked where he begins when writing Leonardo, Donatello, Michelangelo, and Raphael, Langen shares:

“The obvious answer – which, in a happy coincidence, also turns out to be the correct answer – is the comic books… but ALSO the first animated TV series.”

For Langen, the characters and their personalities were born in the original Mirage Studios comics by Kevin Eastman and Peter Laird, and any film version had to respect that DNA.

“You see, the turtles’ characters – their personalities – were first formed in the comic books. And since that’s where they begin, that’s also where you must begin as a writer.”

It’s a philosophy that shows up clearly in both the first and second films. Langen’s focus always remained on the characters themselves.

“At the end of the day, people don’t fall in love with plot. Audiences do NOT come back… because of plot. THEY COME BACK FOR THE CHARACTERS.”

(Readers can learn who the performers were behind the Turtles themselves on IMDb.)

Balancing Action and Heart

From the first film to the sequel, both are grounded in a balance of action and heart, something Langen says wasn’t formulaic, but instinctual.

“This was never really a “conscious” thought process on my part.  I used to be an engineer (aerospace) before I became a screenwriter, so I know how to parse things in mathematical terms… but I never thought to myself, ‘Hmm, I need X% action and Y% heart in this movie’” he explains. “One of the things you sub-consciously monitor while you’re formulating structure, outlining beats, then finally actually scripting a scene is ALL the ‘balances’”… Where am I at?  Am I going too heavy on one and not enough on the other?  You develop a feel for it.”

Writing Splinter: Philosophy in a ‘Kid’ Movie

Splinter anchors the Turtles’ mythology and plays a central role in guiding their journey.

“For me, Splinter was an opportunity to inject a little Eastern-flavored philosophy into the proceedings – an idea I relished in a ‘kid’ movie.”

Langen cites the television series Kung Fu starring David Carradine as an early influence, particularly the main character Grasshopper’s many mentors. “I always thought these ‘masters’ were cool.”

“So I thought about that occasionally while writing Splinter. His is the ‘higher’ voice. The one trying to train the mind, and not just the body.”

And he notes:

“Once you establish a serious character like this… THEY BECOME COMEDY GOLD. Because when they finally let loose with a punchline, the contrast greatly enhances the humor.”

That tonal flexibility is part of what made the original films resonate with multiple generations.

“They’re Fun.”

Why do the Ninja Turtles still connect with audiences more than three decades later?

Langen answers, “THEY’RE FUN!”

He credits their “free-wheeling, happy-go-lucky, wise-cracking, anything-goes ability to be Reptiles That Just Wanna Have Fun.”

That freedom, he says, gives their dramatic moments even more impact by contrast.

And that’s why audiences are still showing up.

The Raphael Sketch Kevin Eastman Drew During a Marathon Story Session

Of all his memories from the development of The Secret of the Ooze, one stands above the rest to Langen.

Kevin Eastman and Peter Laird had contractual story approval – a rarity in Hollywood – which meant Langen could not start actually writing a script until Kevin and Peter had signed off on the story, so they had story meetings at Mirage Studios in Northampton, Massachusetts.

“And it was way cool,” Langen recalls. “We sat in a conference room (let me de-glamorize this, in the basement) and talked about Story for hours at a time.”

“Here’s what I want to emphasize about Kevin and Peter:  These guys were used to working, obviously, in comic books.  And while this often forced me into the role of being the guy who had to say, ‘We can’t do that – this is a live-action movie’ the flipside of that was that these guys were foot-loose (no pun intended) and fancy-free in the Creativity Department… throwing ideas at me left and right non-stop for hours at a time.”

Then, at the end of one especially idea-packed session, Eastman handed him a sketch.

“It was a sketch of Raphael tied to a stake by the Foot (just like in the movie, as we had been discussing)…



except this Raphael was being threatened by every weapon type known to man – ninja and otherwise (the WW1 era machine gun was a nice touch) – which Kevin had sketched in from every edge of the frame, all pointing at Raph, who, in a panic, was screaming, ‘Guys?!  Ah, GUYS…!!’”

Below it, Eastman had written:

“Todd: Are you sure we can’t use this scene?”

“It was an acknowledgement,” Langen says, “that they had been firing a lot of ‘salvos’ at me that day.”

He still has the signed illustration.

“It’s my most prized souvenir from that whole Story process.”

35 Years Later

Looking back now, Langen says the ongoing enthusiasm still surprises him.

“NOBODY SAW THIS COMING.”

He remembers watching a rough cut of the first film decades ago and having no sense of what would follow. The phenomenon that would carry through two films and beyond wasn’t something anyone could calculate.

And yet here we are: new audiences discovering the film, longtime fans bringing their families, and the sequel returning to theaters in a restored 4K presentation.

“I meet fans of the original TMNT movies who say the most outrageously kind things to me – the kind of things where I sometimes have to raise my hands in front of my chest, palms outward, and intone, ‘Too much, too much…’”

“OF COURSE, it’s incredibly gratifying and you’d think I’d be used to it by now,” he says, “But I’m not. It still shocks and surprises me… in the very best way possible.”

Where the Turtles Go From Here

When asked where he’d like to see the Turtles go next, Langen points to where they’ve always been.

“Four characters – brothers in arms and shells – which means they have potential for Comedy (‘brothers’), Drama (‘in arms’), and Emotional Depth (their ‘shells’ making them uniquely alone in what can be a harsh world). What more do you want?”

Then in classic Turtle fashion, he closes with a line only someone who helped shape the TMNT legacy could deliver:

“THANKS-ABUNGA!”
