When I was a kid,I would cry every time I saw the ending of this movie.I couldn't help feeling sorry for the monster,dying alone in a world he never knew. Ray Harryhausen was at his best when he designed the Rhedosaurus. This was a monster with a personality,and dare I say it,charm? Every little movement of the beast almost made you think you were watching an actual living creature,and not some stop motion puppet,like the awful Giant Behemoth. My favorites: the beast sniffing at the lighthouse before he knocks it down;the way he playfully bats at the wrecked car he stepped on,when he turns his back and lashes his tail at the shotgun toting cops,even the way it squints its eyes in the sun.The death scene was well done,and the music,as the flaming roller coaster collapses behind the beast's dead body,still sends a chill up my spine. The worst part of the movie was the casting,especially the male and female leads. Paul Christian's accent is almost impossible to understand at times,and his acting is wooden.Paula Raymond may seem pretty by '50's standards,but I think she has a pronounced overbite and adenoids,the way her mouth is always hanging open! Her acting was also pretty limp.Cecil Kelloway was a delight,as usual,and Ken Tobey was unusually restrained,not trying to hit on Raymond,as he seemed to do in most of his movies. The funniest line in the movie was Kelloway asking Tobey:"What makes you think there are no flying saucers?"(A dig at Tobey's role in The Thing.)Still in all,this is timeless sci-fi classic that holds up well,even today.
