apart from what big Bazz said heres my advice, just my opinion take it or leave it,
sorry i dont get the spine at all?
why do godfather and goodfellas merge on one span? written and directed by different people two different film companies.
i cant see the connection except they are both gangster movies. why 2 cases for goodfallas? is it a 2 disc set? i think it would be better in one 2-disc case
i would make the spine say something like the classic gangsters/mobster collection or what ever you think is best across the spine and then put the titles of each in the normal way.
l would lose the dvd logos from the spanning spine (too repetitive) and lose company logos from the spine (looks messy being different)
Sorry for my English, i'm from Leicester innit?
