The one you are reporting is a film page for the 2 episode mini-series that aired in 2015. 586924 is a feature length film from 2016, which follows the 2015 miniseries. The tv page for the miniseries is already here.

TMDB used to allow miniseries in the film section at one point, but we got rid of that exception; so, we have a bot that can merge the data from the film page to the tv page and then get rid of the incorrect film page. I'm going to be adding this title to that list, so the bot can merge the data over, at an undetermined future date. Thank you for the report.

Since this is a duplicate of miniseries, IMDB of the 2016 film should be removed from here and moved to https://www.themoviedb.org/movie/586924-sp instead
