As other viewers have commented, I personally viewed this film when I only paid 35 cents for admission and it was well worth it. John Wayne was my idol and just the thought of going down under the water was extremely unimaginable and fighting all the horrible creatures we just read or heard about was never viewed on a big screen. (Radio was our only big entertainment and we had to use our IMAGINATION!) In 1948 the country had just gotten over WW II and Hollywood did not have all the special effects it has in 2000! I have viewed this film over and over again and still remember how it kept me on the edge of my seat. All future generations will do the very same thing and admire how much the film industry has advanced in their technology. This is a great John Wayne Classic and to find fault with it is uncalled for.
