The cast of "The American Society of Magical Negroes" all seem to be in agreement that white people shouldn't say the title in full -- and that goes for our own camera guy too.
David Alan Grier made that perfectly clear in a walk-and-chat we did with him Thursday at LAX -- where he was on his way to Sundance to screen his and Justice Smith's new dark comedy ... which is sort of a goofy spin on 'Harry Potter,' but with historical racial tropes.
Just watch the trailer to get the gist of what it's actually about -- it's pretty self-explanatory -- but on the issue of saying this film's title in full .
.. DAG is on the same page as Justice. Namely, he also thinks whites should steer clear of letting it come out of their mouths.
You'll recall ... JS -- who's the lead star of the flick -- yesterday at the airport, although you can tell he's totally joking. Ditto for Dave ... or so it seems?!?
Check out this back-and-forth he has with our photog ... let's just say, it's a bit awkward.
Charlie here is a white dude, and he doesn't wanna offend anyone -- but when David dares him to say the film title in all its glory .
.. things get a little handsy, all in good fun, though.
