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.

But when the show first premiered, the two were uncredited in the opening and left out of the theme song, referred to simply as “the rest.”
