king solomon's mines (1937)

"Volcanoes are nervous things, it takes so little to upset them."
Kathleen's (Anna Lee) father runs off in search of Solomon's jewels in the unexplored African interior. Fearing for him Kathleen convinces hunter Allan Quartermain (Cedric Hardwicke) to follow and bring him back. Whilst on their journey they come across Umbopa (Paul Robeson), who unlike the other bearers asks no wage and acts aloof.
Despite the initial deviation from the original story this is a fairly faithful retelling of the adventure, with added operatic ballads provided by Paul Robeson.

the island at the top Of the world (1974)

"If I told you, you would think I was mad."
1907 and four men become explorers as one bankrolls a search for his missing son, lost in the arctic. Using an airship they chance upon a colony of Vikings, and a heap of trouble.
Gung ho, but perfunctory adventure tale, that never really sparks the imagination.
