I think it would be a surprise if they actually released anything. If they were to I would guess films like Sunset Boulevard, Chinatown, Once Upon a Time in the West, The Odd Couple, To Catch a Thief, Airplane!, Ordinary People, Rosemary's Baby, Love Story, Roman Holiday, An Officer and a Gentleman, Flashdance, Terms of Endearment, The Greatest Show on Earth, Urban Cowboy, Marathon Man, Wings, War of the Worlds, Harold and Maude, Serpico, Breakfast at Tiffany's and some more John Wayne titles would be considered. This is a partial list of Award Winners and box office hits they own. The Pre-1950 films Universal owns.
I'd personally like Nashville, Hud, The Miracle of Morgan's Creek, Seconds and Wonder Boys. They seem like Criterion titles in my opinion.
