Journey to the Center of the Earth (1959)

Edinburgh university professor Sir Oliver Lindenbrook believes he has found an very old message from a long lost scientist who may have found the way to journey to the center of the Earth. With his assistant, student Alec McKuen, he sets off for Iceland where an entrance in a volcanic range is to be found. They are soon joined by Carla Goetabaug, whose scientist-husband was recently murdered, and Icelander Hans Belker as they descend into the bowels of the Earth. There they will find fantastic creatures, exotic plants, the lost city of Atlantis and a foe who wants to keep knowledge of this underworld to himself.
