Where is the DVD?

This enjoyable film has it all - a good plot, exotic locale, the lovely and statuesque Ursula Andress in her prime, and a juicy cameo by the great Orson Welles. Is is a shame that it hasn't been released on DVD (or video, as far as I can remember). Usually, that involves a problem over the rights. I saw it when it came out and later on television and enjoyed it both times.
