this be one of the thoroughly enjoyable monster movie that appear amid all the camp and trash the genre churn out in the 1950s . while it be no masterpiece and there be nothing worthy of serious criticism . the movie be well pace with plenty of action the viewer be not require to wait 45 minute before anything at all happens . it be very well film and in a widescreen format ( the only way it should be see ) . and the acting by an exceptionally attractive cast be above average for this kind of film . a for the dinosaur and they may not be up to the standard of jurassic park or walk with dinosaur and but and again and consider what the budget must have be and they be rather good ( except for a slow move tyrannosaurus ) . what really make this movie worthwhile be it atmosphere . it draw the viewer into the reasonably convincing world of a tropical jungle in the middle of a polar icecap . a very likeable and exciting movie . see it in widescreen if you can .
