Actually, TMM is open-matte. I have a copy. I don't know about GMC or MTI, but MCC looks like it *might* be open-matte too. I have three different copies of this: the UK DVD release, the US letterboxed laserdisc, and an anamorphic broadcast from UK TV. The framing on the laserdisc is different to that of the broadcast, indicating that there is definitely some picture material outside the selected 1.85 area, and a good many shots (although by no means all) of the 4:3 DVD are in fact the same width as the widescreen, simply including more picture at the top/bottom of the frame.
