You’d be hard pressed to find a modern movie lover who doesn’t own at least one DVD/Blu-ray from The Criterion Collection. With a catalogue of hundreds of auteur and contemporary titles, Criterion is just as much about preservation as it is curation.

This video from Gizmodo takes you behind the scenes at Criterion’s Gramercy office and inside the process of restoring Alfred Hitchcock’s Foreign Correspondent. Beginning with a negative from the Library of Congress, the print is scanned, color corrected, retouched and sound edited before making its way into one of the company’s signature disc covers.

I recently visited the office to interview Paolo Sorrentino and can confirm that there are indeed magical fairies manually retouching a given print’s frames.
