10 Creepiest Movie Mistakes Ever

There's a strong argument to be made that last year's big-screen Cats adaptation is one big creepy mistake, largely due to the wholly unconvincing attempt to transform A-list actors into anthropomorphic felines courtesy of not-so-cutting-edge visual effects.

Beyond that, the film hit screens effectively unfinished, with a "patch" even being sent to cinemas to update the wonky effects shortly after release - albeit by which point the critical scorn had basically torpedoed the movie anyway.

Though the effects were reportedly touched-up for the home video release - few have seemingly convinced themselves to watch it again and find out - Universal still let a number of VFX gaffes from the cinema version make it into the "final" cut.

Surely the most infamous and offputting mistake occurs in the film's climactic musical number, "Finale: The Ad-Dressing of Cats," where Old Deuteronomy (Judi Dench) can be seen wearing the actress' real wedding ring in numerous shots.

Evidently, the VFX team were so thoroughly overworked through post-production that they missed this widely-ridiculed mistake, which only reminds audiences that, indeed, the very human Judi Dench is scarcely visible beneath that digital cat-person abomination. Terrifiyng.
