Pixar is known for its feel-good family classics with plenty of moments that pull on the heartstrings.
But what if something darker is actually lurking beneath the surface of one of its all-time greatest children's films?
That was the question asked by the Just The Nobodys Podcast about Finding Nemo, reports the Mirror.
A clip of the hosts discussing the movie was shared to TikTok, where it racked up a staggering 19.3 million views.
They said: "Have you ever heard of the Finding Nemo theory? This is going to ruin your day.
"So, we all know the movie Finding Nemo is about a father fish named Marlin and his son Nemo, and it's Marlin's journey in finding Nemo after he was taken by scuba divers.
"There's a theory that Nemo's not real and never existed. It's actually Marlin's imagination because he's grieving over the death of his wife and all his kids.
"And to make everything worse, the word Nemo in Latin means no one.
"Disney's literally telling the audience we have a movie called Finding Nemo but it actually means finding no one, because Nemo's not real.
"That's why Dory is such a good friend for Marlin, because she has short-term memory loss and can't remember that Nemo's not real."
Social media users were quick to comment, with one saying: "I should have just scrolled".
Another added: "This really did ruin my day what is it."
But others poked holes in the dark theory, with one arguing: "This isn't true. What about the other fish and humans that interacted with Nemo?"
Finding Nemo was released in 2003, starring Alexander Gould as the voice of Nemo and Albert Brooks as Marlin.
