Who are the Characters of Journey to the Center of the Earth?
The movies differ from the Verne Novel. There is essentially Professor Lindenbrook- the Scientist and head of the expedition, his assistant, who was miscast as Pat Boone in the movie- which was fine for several songs having nothing to do with the plot lines- The Female character- who is the widow of some explorer- and is bankrolling the expedition- there are no girl characters in the Verne novel- I"m glad Hollywood brought one in- The Bad Guy scientist- also with a Scandinavian name- and the muscular Lars who is the handy-man of the Expedition.- Oh yes, Bad guy was only ever referred to as 'Count Sagnussen'. These same characters existed in the TV Cartoon by Donald Sutherland- and pretty good for its type. Gertrude the Duck remained alive as a comedy interest in the cartoon- the duck was killed and eaten by the bad guy in the movie. The scientists work out of Edinburgh University, which is in Scotland, in spite of the Scandinavian names. I met Arlene Dahl last year at the Loew"s showing.
