Which box sets from Amazon (UK) play in the United States?

[XXXsdesdeXXX]

I have noticed, as many others have, the huge price gap between U.K. box sets and U.S. box sets. In some cases, as I have read, the U.K. set is exactly the same in quality as the U.S. set and is region-free NTSC. The reason I have made a thread is because I wasn't able to easily find out which U.K. box sets play in U.S. players. I apologize in advance if this is a repost, but I wasn't able to find any other existing thread that answered these questions. I also noticed that some of the region information for any particular box-set on Amazon.co.uk can be wrong, so I think anecdotal evidence would be in order. A few that I am interested in, but am unsure of, are:

The Ultimate Bourne Collection [Blu-ray] [2002]

Band Of Brothers - HBO Complete Series [Blu-ray] [2001]

The Matrix/Matrix Reloaded/Matrix Revolutions [Blu-ray] [1999]

Mission Impossible: Ultimate Missions [Blu-ray] [1996]

The Mummy 1, 2 & 3 Box Set [Blu-ray] [1998]

I would appreciate a listing of any box set, that is not listed here, that plays in the United States. I would prefer listings of items that are less expensive then their counterparts in the United States since this list could get long.
