ON THE COMET was the only film of his, besides JOURNEY and JULES VERNE, that I could find a VHS release listed as being available in the NTSC format. Unfortunately, unlike JOURNEY AND JULES, I never found a place that carried it. Given that the VHS format appears to be an endangered species, and that no one seems to be offering any of Zeman's films on DVD, I may see if the local video chain can special order it for me. Even animation pioneer Lotte Reiniger has been given the DVD treatment, with her 1926 ADVENTURES OF PRINCE ACHMED available from Image (with a silent film ad for soap and a featurette on the filmmaker included), while her 1921 STAR OF BETHLEHEM appears on a couple of compilations of public domain Christmas shorts.
