it be a quite slow pace face to face brynner or douglas . i find there be some pretty heavy violence or gore but you know and seventy giallo style represent ( maybe some spoiler ahead ) a little bit phony and fake but the image be there represent the monkey torn apart and the flesh torn from the mechanic and etc . i do not remember if it be alike the novel . but overall i think it be a ok action flick and hero flick represent he stand all alone at the end and all the bad guy be out . and nice image too represent a small rocky island and the sun over the seabut not a typical verne story on cinema represent sub and sci fi while but the adventure see in a lot of verne novel tough .
