I have been waiting since 1969 to see this, since it wasn't available on tape, and finally saw it on DVD on widescreen TV, home theater sound, etc, to get as close to the movie theater experience as possible. Too bad, because while the spectacle of all the adventure and effects are grand, the acting, dialog and direction borders on insipid. The director, Kowalski, was interesting with his two 50's sci-fi horror flicks, he was and has been basically a TV director and it shows here. He never really uses the big screen, not to mention Cinerama, to it's potential. He doesn't use the great (like Sal Mineo) and good (like Brian Keith) actors to their full potential. The effects are nice enough, but the same shots are used too often. Where there should be build up of suspense, there's only tedium and passing the time, much like typical 70s network TV fare. The writing is uninspired and much of the dialog is weak. There's plenty of dramatic plot elements to bring together and hit us in the gut, such as the woefully unexplored relationship of Mineo and Jacquie Chan, and this would have been great with a director the caliber of David Lean or Robert Wise. The first 15 minutes are very good and made me think it would be as good as, say, The Sand Pebbles, but alas, no. In the hands of an inspired talent, I dare say it could have had several academy award nominations, including Brian Keith for supporting actor, and it could have run nearly 3 hours and still have been engrossing. Well, MGM wasn't up to snuff in 1968-69, and so this is what we got. Normally, I'd give a 6 to a film like this, but it gets 4 because of all of the wasted potential. Could be a good remake though!
