Are there any dirty scenes in the movie the little mermaid?

Answer 1

No.

The infamous moment in which a priest is supposed to have an erection visible through his cloak is simply a case of a screen shot taken out of context. The "erection" is actually the priest's stubby knee cap. The character has skinny legs with stubby knees which is clearly visible in most of the shots. When that one still is viewed, one can reluctantly see how it could appear to be an erection, but when viewed in the context of the movie, it clearly is not.

However, the movie does have a few brief flashes of nudity when Ariel is first changed into a human. Immediately after the metamorphosis, she is shown from a distance in shadow and is clearly nude from the waist down. When Flounder and Sebastian race to bring Ariel to the surface (now that she can no longer breathe underwater) there are three to four frames in which Ariel's bare butt is visible. Later when she first stands on her new human legs she is briefly shown nude from the waist down again, though the shot moves away from her before she is standing up so nothing can actually be seen.

That is the closest THE LITTLE MERMAID comes to having any "dirty scenes."
