The movie exception is for 100 fics on AO3 and Stardust 2007 only has 59 works so nudging it that way wouldn't work because it's unfortunately ineligible any way you slice it. 78 works for Stardust - All Media Types without putting in filters. 25 works for Stardust - Neil Gaiman without any filters. And on FFN, 48 fics in movie version and 30 fics in book version.

Unfortunately, unless you provide other evidence, Stardust is currently a fandom sized for Yuletide and Night on Fic Mountain.
