I know that a remastered version of this film is being released by Paramount in Region 2 (PAL) next month. If the release is decent, it should come out sometime soon in Region 1 (Then again, "The Italian Job" was cancelled/pushed back by Paramount for Region 1 so who knows what's up with Paramount and their releasing schedule.)
It's ironic that I suddenly find myself in a better position here in Europe, when it comes to classic Michael Caine flicks! I've had to order The Ipcress File and Alfie from Canada, back when there weren't any anamorphic versions of them this side of the pond. I guess that Paramount figured that there is more appreciation to be gotten for the films on the British market. Which is probably true.
There are already a number of non-anamorphic "cheapie special" versions on the market here, so I'm afraid MGM feel that that a decent DVD wouldn't sell well - I'd certainly buy, however.
