Five years before Jurassic Park roared into theaters, a gentler, more meditative dinosaur film endeared itself to audiences of all ages. Initially met with mixed reviews, The Land Before Time is now regarded as an animated classic. Here are 10 things you might not have known about the Steven Spielberg-produced film, which arrived in theaters 30 years ago.

1. IT WAS CONCEIVED AS A DIALOGUE-FREE MOVIE.

Universal Pictures Home Entertainment

In the mid-1980s, executive producer Steven Spielberg began toying with the idea of a Bambi-esque dinosaur film. “Basically,” he later said, “I wanted to do a soft picture … about five little dinosaurs and how they grow up and work together as a group.” Inspiration came from the “Rite of Spring” sequence from Disney’s Fantasia (1940)—a scene in which prehistoric beasts wordlessly go about their business. At first, Spielberg wanted his own dinosaur characters to follow suit and remain mum. Ultimately, however, it was feared that a non-verbal approach might bore or confuse the film’s intended audience. As such, the animals were given lines.

2. DIRECTOR DON BLUTH WAS AN EX-DISNEY EMPLOYEE.

Don Bluth grew up idolizing Disney’s work, and began working for the studio in 1955. Over the next two decades, he did various odd jobs until he was brought on as a full-time animator in 1971. Once on the inside, Bluth got to peek behind the magician’s curtain—and disliked what he found there. “I think [Walt Disney] would’ve seen that the pictures were losing their luster,” Bluth said. Frustrated by the studio’s cost-cutting measures, he resigned in 1979. Joining him were fellow animators Gary Goldman and John Pomeroy. Together the trio launched their own company, Sullivan Bluth Studios, and began working on The Land Before Time in 1986.

3. OVER 600 BACKGROUND PAINTINGS WERE MADE FOR THE FILM.

Most of these depicted beautiful but barren wastelands, which presented a real challenge for the creative team. As one studio press release put it, “The artists had to create a believable environment in which there was almost no foliage.” Whenever possible, Bluth’s illustrators emphasized vibrant colors. This kept their backdrops from looking too drab or monotonous—despite the desolate setting.

4. LITTLEFOOT’S ORIGINAL NAME WAS “THUNDERFOOT.”

This was changed when the filmmakers learned that there was a triceratops in a popular children’s book called Thunderfoot. Speaking of three-horned dinosaurs: Cera evolved from a pugnacious male character called Bambo.

5. THE FILMMAKERS HAD TO CUT ABOUT 10 MINUTES OF FOOTAGE.

“We compromised a lot with The Land Before Time,” Goldman admitted. Nowhere was this fact more apparent than on the cutting room floor. Spielberg and his fellow executive producer George Lucas deemed 19 individual scenes “too scary.” “We’ll have kids crying in the lobby, and angry parents,” Spielberg warned. “You don’t want that.”

6. “ROOTER” WAS INTRODUCED AT THE URGING OF CHILD PSYCHOLOGISTS.

In Bambi, the title character’s mom dies off-screen. The same cannot be said for Littlefoot’s mother, whose slow demise goes on for several agonizing minutes. Naturally, there was some concern about how children would react to this. “A lot of research went into the mother dying sequence,” Pomeroy said. “Psychologists were approached and shown the film. They gave their professional opinions of how the sequence could be depicted.” Thus, Rooter was born.

One scene after Littlefoot’s mom passes, the wise reptile consoles him, saying “You’ll always miss her, but she’ll always be with you as long as you remember the things she taught you.” Sharp-eared fans might recognize Rooter’s voice as that of Pat Hingle, who also narrates the movie.

7. JAMES HORNER DID THE SOUNDTRACK.

The late, Oscar-winning composer behind Braveheart (1995), Titanic (1997), and Avatar (2009) put together a soaring score. Along with lyricist Will Jennings, he also penned the original song “If We Hold On Together,” which Diana Ross sings as the end credits roll.

8. THE ACTRESS BEHIND DUCKY PASSED AWAY BEFORE THE MOVIE’S RELEASE.

Judith Barsi’s career was off to a great start. By age 10, this daughter of Hungarian immigrants had already appeared in 70 commercials and voiced the leading lady in Don Bluth’s All Dogs Go to Heaven (1989). For The Land Before Time, Barsi voiced the ever-optimistic Ducky, which was reportedly her favorite role. Then tragedy struck: In July of 1988, Barsi’s father József murdered both her and her mother before taking his own life.

9. IT HAD A RECORD-SETTING OPENING WEEKEND.

From the get-go, The Land Before Time had some stiff competition. Universal released it on November 18, 1988—the same day that Disney’s Oliver & Company hit theaters. Yet, for a solid month, Bluth gave Oliver a box office beating. The Land Before Time enjoyed the highest-grossing opening weekend that any animated film had ever seen, pulling in $7.5 million to Oliver & Company’s $4 million. Since then, of course, The Land Before Time has long been dethroned; today, Incredibles 2 (2018) holds this coveted distinction with a $182.7 million first-weekend showing.

10. THERE ONCE WAS TALK OF A LAND BEFORE TIME STAGE MUSICAL.

“The time has come for dinosaurs on Broadway,” the late theatrical producer Irving Welzer told The New York Times in 1997. Emboldened by the recent cinematic success of Spielberg’s The Lost World: Jurassic Park (1996), Welzer expressed an interest helping Littlefoot, Cera, Ducky, and the rest of the gang make their Big Apple debut. Soon, however, the idea faded.
