Well then a disclaimer/public service announcement is needed on the opening
(not buried in the credits like the "No animals were harmed" bit) of the movie.
Pointing out that Drow are black skinned elves because they're inspired by the Dökkálfar out of Norse mythology, and that they are NOT a stand-in for any color of Humans.
Audiences can then be directed to the real world source(s): the Prose Edda & the Hrafnagaldr Óðins.
See? D&D is good for you. You learn things!
Personally, I would dress this PSA short up as the narrator - Volo/Elminister/a bard/etc - turning to directly address the audience in order to give them a piece of context about where he drew his inspiration for the tale to be told from.
Maybe even directly read a passage to the audience from an actual RL book they could track down.
And just to be humorous? I'd open the segment with the title plate "They say knowing is half the battle."
And end it with "And now you know."
(yes, I know that isn't the exact quote/sequence)
