Received the boxed set a week ago. I display it with Vol. 1 on my shelf. None of the reviews mention the excellent bonus disc with lots of short films, including a 3 Stooges short, a Charlie Chase short, a couple of Mr. Magog cartoons, a Lisbon travelogue and many others. I went back and noticed that Vol 1 also had a disc which was tucked inside the box next to 3 of the UHD disc boxes. I’ll have to check the menu out to see what is included there.
