Neither have I ... in the sense I suspect you intended: as a 3D movie.

I've seen (and own) several that were released as "3D" movies.
/Creature from the Black Lagoon/ comes with a trailer proudly
proclaiming it as the first 3D movie to be filmed underwater. /Dial
"M" for Murder/ is (AFAIK) Hitchcock's one and only forey into=20
"3D" (that's why the image has the woman's hand pointing at you: it no
doubt extends from the screen in "3D"). /Coraline/ is not only "3D";
the DVD comes with a packet of "red/blue" paper eyeglasses and has two
sides: one "3D" and the other the side I watch. And of course
Argento's /Dracula/ and /Harry Potter and the Deathly Hallows Part 2/
are "3D". And there are many many others.

But I watch none of them in 3D. I have my own glasses and don't need a
second pair to fix the blurriness of the film. (I am relying here on a
scene in /The A-Team/ which depicts what a "3D" film looks like
without the glasses.)

/Coraline/ is interesting because it points out the /real/ purpose of
"home 3D": to make money by requiring a new, special BD player and a
new, special TV set -- neither of which was necessary, just a
properly-prepared disk. But that's just how it goes nowadays.
