Alfred Hitchcock Masterpeice Collection… which version of North by Northwest?

[Captainhawk1]

Hi! I have had the Alfred Hotchcock Masterpiece Collection for some time now but before I purchased it, I had the 50th Anniversary Edition of North by Northwest, as well. Does the collection contain the same version? Are there any differences between the version in the set and the version I had beforehand with either the film itself or the special features?

I'm just curious because I'm cleaning out some Blu-rays that I have dupes of to make room and if they're the same there's no reason to keep the single disc.

Thanks in advance.
