The 1960 film Swiss Family Robinson was based on the 1812 novel by Johann David Wyss, making the adventure story nearly 150 years old by the time Walt Disney Productions adapted it for the screen.

Disney’s version of Swiss Family Robinson was not the first movie adaptation of the story. An earlier film version had already been produced in 1940 by RKO Pictures.

The film marked an important technical milestone for Walt Disney’s studio because it was the company’s first widescreen live action movie filmed using Panavision lenses instead of its usual widescreen techniques.

When Swiss Family Robinson premiered on December 21, 1960, it was made on a $5 million budget but eventually earned around $40 million worldwide, making it a huge financial success for Disney.

The story begins with a Swiss family fleeing the chaos of the Napoleonic Wars, which provides the historical backdrop for why they were traveling across the ocean in the first place.

In the film’s story, the Robinson family uses a clever trick to scare away pirates by raising a quarantine flag and pretending their ship is infected with the deadly disease known as Bubonic Plague.

The famous treehouse from Swiss Family Robinson was built inside a real 200 foot tall saman tree during filming and was strong enough to hold dozens of crew members and actors at once.

After filming wrapped, locals convinced Disney not to dismantle the treehouse set, and it briefly became a tourist attraction until it was destroyed by Hurricane Flora in 1963.

The majority of the film was shot on the Caribbean island of Tobago, which the filmmakers discovered almost by accident after searching through several other potential filming locations. Director Ken Annakin reportedly fell in love with Tobago the moment he saw it and immediately knew it was the perfect island setting for the Robinson family’s adventure.

Ironically, although the island looked like a paradise jungle, Tobago originally had very little wildlife suitable for the story, so Disney had to import animals from all over the world. The film’s animal cast was enormous and included eight dogs, forty monkeys, two elephants, six ostriches, four zebras, six hyenas, two anacondas, and even a tiger.

Over a dozen professional animal trainers were hired to manage the film’s animals, and they held daily meetings with the director to plan the animals’ actions for the next day’s scenes.

Actor John Mills once joked about the brutal filming conditions, saying a normal workday involved avoiding scorpions, quicksand, land crabs, snakes, sharks, and sunstroke just to get a shot.

The famous animal race scene around the treehouse required special close up shots that were filmed later in January 1960 after the main filming schedule had already ended.

The production of Swiss Family Robinson required building both outdoor sets on Tobago and indoor replicas of the shipwreck and treehouse at studios near London.

During production, a wage dispute broke out between Disney and the British film crew, and union negotiations had to settle the disagreement so filming could continue.

Several local Tobagonians were hired as drivers, assistants, and even stunt doubles for the actors during filming.

The film ended up being the fourth highest grossing movie of 1960 based on domestic rentals in the United States. In the United Kingdom, Swiss Family Robinson became the single biggest box office hit of 1961.

Actor Tommy Kirk later said the film was the project he was most proud of in his entire acting career.

The adventurous story and giant treehouse helped inspire later Disney attractions, including the walk through treehouse experience at Disneyland Park.

In 2019, Disney added a content disclaimer to the film in its streaming catalog due to criticism of racial stereotypes in the portrayal of some pirate characters.

Plans for a remake of the story were announced in 2004, with Disney exploring new versions of the Robinson family adventure. One version of the remake was reportedly going to star the real life family of Will Smith and Jada Pinkett Smith along with their children. Although the planned remake never materialized, elements of the concept eventually influenced the 2013 science fiction film After Earth, which starred Will Smith and Jaden Smith.
