"Only took me 20 years to realize," Radicek wrote on Reddit, pointing out the wizard's pipe was hiding in plain sight, inside his original staff the whole time.

But before they tie the knot, Fiona nearly marries Lord Farquaad, voiced by John Lithgow, with one scene showing him looking at footage of his bride-to-be.

Despite being released more than 30 years ago, one fan spotted an "Easter egg" in the original movie, referencing the Doc and Marty's time travels.

TikToker @Hiddenmoviedetails shared a clip, saying: "Did you know that in Back To The Future, made in 1985, when Marty is first meeting up with the Doc to see the DeLorean, he's meeting up at Twin Pines Mall.

From a children's film to one for adults, the book-turned-film trilogy, 50 Shades, features a tribute to Dakota Johnson's mom.

The actress, who played Anastasia Steele, is the daughter of Melanie Griffiths, who is best-known for her starring role in the 1988 film, Working Girl, as Tess.

In the movie, Tess turns to a female colleague and utters an iconic line, which Johnson repeats nearly word-for-word, only changing the name, in Fifty Shades Darker.

The homage was picked up by fan Christasia, who shared side-by-side clips of both films to TikTok.

'The Matrix' Fans Are Only Just Noticing This Very Obvious Mistake in the Movie

Matrix fans are getting ready for the next installment of the franchise, The Matrix Resurrections, but one fan spotted something amiss in the original.

An undisputed masterpiece, the 1999 flick features the characters—including Neo aka Keanu Reeves, and Trinity, played by Carrie-Anne Moss—firing a substantial number of weapons.

But movie buff Glt23 spotted an error, and shared a snap on Reddit, captioned: "In The Matrix (1999) you can see a full blank coming out of the pistol as Neo is shot the second time. I've seen this movie many times and [it's the] first time I had caught this."

'Frozen' Fan Spots X-Rated Moment in Disney Classic

Another Disney movie makes the list, Frozen, and it's a similarly risqué scene which was picked up by viewers.

The singalong showstopper features Anna and Elsa as the main characters, with one scene showing the younger sister chatting with Kristoff, on a sleigh ride.

Professing her love for her new fiancé, Kristoff quizzes her, asking her what his shoe size is.

"Foot size doesn't matter," Anna replies, widely thought to reference the urban myth that shoe size is linked to the size of another part of the male anatomy.

Martinez shared the clip to her TikTok page, as part of her "childhood films filled with adult jokes" series.

With Carrie the protagonist, the intro featured her on the streets of New York getting splashed by a bus.

But TikToker, Kara McLean, spotted two continuity errors, the first being the bus which soaks her is miles away from the curb, and the passengers all mysteriously disappear as the vehicle turns the corner.
