Perhaps the data editor misunderstood and thought you were trying to list an award nomination as trivia (if this film gets that far, it should be added to the awards page, not as trivia). But as this is just selection for consideration, much earlier in the awards process, I think it probably should be valid as trivia.

Thanks for your message. It is IMDb policy to not accept awards entries as trivia items when they can be added to the awards section, however in this case the submission is valid. I've added this on your behalf now which will go live shortly.
