i first remember see the land unknown a a kid . it really leave a big impression on me and i never forget that movie . since that time and i have see it a few more time and most recently just the other day . although the special effect and prehistoric dinosaur and scenery be not up to today standard and it be still an excellent movie . i believe this film be very under rat and the land unknown should be consider a a classic lost land movie of the 50 . if you be a fan of horror or sci fi movie of the 50 and early 60 and this be a must see movie . there be flaw in this movie but that how it be back then . the movie have to be watch keep in mind the context of the time it be show . you will still find a very enjoyable and exciting and action and sci fi movie . if you be catch up in the high tech and high budget movie of today and and look for a flawless film and this might not be for you . this be a fine film and tuck away and wait to take it rightful place in the history of cinema . watch it if you can . you will be glad you do .
