Has anyone heard of a rumor that spliced in amongst some of these films' soundtracks are audio clips from porn scenes featuring these same young actors?

If "conspiracy" can ever be said to just be for entertainment, then here's something along those lines: a paper from (known disinfo agent) Miles Mathis exposing JK Rowling as a fake person and speculating the "Harry Potter" series was written by Intelligence:

The Great Harry Potter Hoax (5/15/2016 15-page PDF)

I suppose, though, that we should not fin it entertaining that "Intelligence legends" are floating around universally accepted as real people, and that hidden hands shape our culture from angles we least expect.

Harry (pointing wand): "Jewgamus Apocalypsus!"

Voldemort: (turns Harry into a foreskin) "Fuck off, you little hebe."

Snape: "For once I agree with you!" (high fives Voldemort)

Oh look at the small cap downvoters. lolz.
