From 1964 to 1967, this iconic series transported us to a tropical paradise where castaways faced all sorts of wild adventures. But you know what? Even in that idyllic setting, there were some little mistakes you might have missed!

Gilligan’s Island: the more you know, the better it gets! I can’t believe there were only three seasons, especially considering how incredibly popular the show was and the cult status it still holds today, even into the 2020s.

I know that fans of the series truly love to uncover the bloopers, so here’s a bunch of them for everyone to enjoy. These bloopers you can’t even notice unless you’re looking for them!

Two mysterious people
To begin with, there’s a big blooper that many people have missed during all these years. In season two’s opening credits, we start at the marina, where we’re greeted by the Skipper and, of course, Gilligan. The scene then takes us to the boat setting sail into the vast ocean, ready for their infamous ”three-hour tour.”

Now, here’s where things get interesting. We all know there should be seven castaways, right? But if you take a closer look at two separate shots in the opening credits, there are actually eight people on the boat!

So, who are these mysterious extras? Turns out, they’re stand-ins, used just to get those wide shots from a distance. The real actors weren’t actually on the boat for these particular scenes, and those extras helped make the magic happen, according to some reports.

This sneaky blooper has been missed by many fans, but now you’re in on the secret!

The friendly physician
How many of you remember the episode The Friendly Physician from season two of Gilligan’s Island?

In this quirky storyline, the castaways are lured to another island by a mad scientist, played by Vito Scotty, who portrays the eccentric Dr. Boris Balancoff. Promising to rescue the stranded group, he secretly plans bizarre experiments, including one where he swaps Gilligan’s brain with Mrs. Howell’s!

The Friendly Physician is the only episode where the castaways actually leave the island — and the only one where they switch bodies.

But here’s a little blooper from the episode you may have missed. During the scene when the castaways are sailing away from the scientist’s eerie castle, take a closer look at the background. You’ll spot buildings from the CBS studio lot!

The lagoon set was carefully designed to hide any traces of the surrounding studios, warehouses, and equipment, with plenty of plants and trees placed to create an isolated island feel. However, in this particular shot, the camera was positioned just wrong enough to expose a peek behind the Hollywood magic, showing parts of the studio lot that weren’t meant to be seen.

It’s a fun reminder that even on a “deserted” island, showbiz can sneak into the picture.

The Kennedy assassination
A rather dark bit of trivia given how silly the show was, but filming the original pilot of Gilligan’s Island, titled “Marooned,” coincided with the assassination of John F. Kennedy in November 1963.

The cast and crew got news of the assassination while wrapping up filming in Honolulu Harbor. The tragedy also delayed filming, as U.S. naval and military bases closed for a period of mourning.

If you look closely at the season 1 intro sequence, you can see US flags in the background at half-mast: they were lowered in honor of the slain president.

Alan Hale rushed to his audition on horseback
It’s hard to imagine anyone else but the great Alan Hale Jr. playing The Skipper — and the actor truly went the extra mile when it came to auditioning.

Hale was in Utah filming the western Bullet for a Bad Man when he received the casting call for Gilligan. According to the book Surviving Gilligan’s Island, Hale snuck off set on horseback. He then hitchhiked his way to Las Vegas, got on a flight to Los Angeles, and made his audition.

Thankfully, the extra effort paid off and Hale landed the role, beating out some tough competition: future All in the Family star Carroll O’Connor also auditioned.

Natalie Schafer opens her eyes
In one memorable Gilligan’s Island episode, Gilligan becomes a butterfly collector when an expert visits the island, more interested in butterflies than rescuing the stranded seven. Naturally, the castaways hatch a plan to trick the expert into helping them get back home.

They even try to get him to drink alcohol, hoping it will work in their favor. But things take a hilarious turn when they all get so drunk on fermented berry juice that they pass out.

Now, here’s where the bloopers comes in: The Professor, who famously claimed to be allergic to alcohol in the episode ”Nyet, Nyet, Not Yet,” drinks the fermented juice along with the others.

And if you look closely during this scene, you’ll catch another little goof — Mrs. Howell, played by the charming Natalie Schafer, briefly opens her eyes while pretending to be passed out. It’s a small slip, but a fun one to spot!

Woodpeckers on oceanic islands
In the very first episode of Gilligan’s Island, Gilligan and the Skipper build a raft and set out to sea in hopes of finding help. But did you know this scene was actually filmed in a movie tank—essentially a giant swimming pool?

If you pay close attention during the shark attack scene, you can spot the rim of the tank peeking into some shots. And when Gilligan gets his oar bitten by the shark, and the Skipper tells him to keep paddling, you might notice the shadow of the boom mic on the raft in the lower left corner of the screen.

But that’s not all! This episode is packed with little quirks. For example, when Gilligan disguises himself inside a tree trunk, a woodpecker starts pecking at his head. Fun detail, right? Except, woodpeckers don’t actually live on oceanic islands.

The original theme song left out The Professor and Mary Ann
It’s safe to say that the castaways wouldn’t have lasted long without The Professor (Russell Johnson) and Mary Ann (Dawn Wells), who were often the brains and voices of reason on the show.
