A film analyst examined data from Sight and Sound magazine's decennial rankings of cinema's greatest works, which aggregates votes from thousands of accredited critics. By tracking how individual films' positions have shifted across multiple decades, the researcher developed statistical methods to identify which movies are declining in critical esteem and at risk of fading from the canon.

Jean-Luc Godard's 1967 avant-garde film Deux ou trois choses que je sais d'elle emerged as most vulnerable to cultural obscurity. The experimental work critiquing 1960s consumer culture maintained top-100 status across four consecutive ranking cycles through 2002, yet has since collapsed—reaching 102nd place in 2012 before falling to 462nd by 2022. Whilst scholars still regard it as significant, its steep decline suggests the unconventional film faces genuine risk of disappearing from future critical discourse, though rediscovery by new audiences remains possible.
