"I remember the braces - they are the punchline to the scene" is how I and several of my deepest fan-boy friends have reacted to my introducing them to this memory-meme.
As much as I am a fan of PKD's "revelation of the matrix" 1977 speech (
viewtopic.php?f=8&t=28108) most of the Mandella Effect examples leave me nodding my head saying, yep - memory is a tricky thing and most of these examples (especially the product logo/name ones) strike me as just plain old fallibility of memory as well as the social re-write nature of the "telephone game" in which stories are altered during the re-transmitting of the memes.
But there have been a couple that have stuck in my craw like this Moonraker Braces example as well as the "C-3PO had a silver leg in the original Star Wars" example! In both of those cases my fan-boy friends and I are left scratching our heads.
I too can imagine the dvd release including digitally modified elements (think of the CGI'd-out machine guns held by the Feds in Spielberg's E.T.) ... but, perhaps it really is just a trick of memory for the braces... my wife hadn't seen Moonraker and when my friend and I watched the dvd bluray version (its what we had on hand) and went to that scene, my wife commented that perhaps the fact that Dolly was wearing glasses and pigtails was enough for most minds watching it at the time to
imagine she had braces, like the overlay of a false "archetypal nerd image" on top of the perception. But that still does not sit well with me because I always remembered that (at least, in retrospect I
believe I've always remembered it that way) as the POINT of the scene, especially with her SMILING to reveal her teeth AFTER the Jaws character reveals his mouthful of metal!
