MA, as in Magnificent Ambersons, of course. And Journey Into Fear.
What have we been told about any moves to release anything, and what were the release dates?
Last year I read elsewhere: "Warner Bros., who owns the rights to "Ambersons" in the U.S. and Canada, has no plans to release the film on a Region 1 DVD anytime soon" (May 2006)
and from WB: "We're still looking for better materials on AMBERSONS. We waited for KONG and KANE and it was worth it. It will be worth it for the AMBERSONS, and yes, we will release JOURNEY INTO FEAR when we do AMBERSONS." (2006)
