1959, Susan Heyward and Jeff Chandler, Thunder In The Sun. A wagon train of Basques emigrate to California, taking their wine grape cuttings with them. It features an odd yodeling call they used to use to carry messages in the mountains, fighting off attackers with jai alai balls bounced off rock faces, and bouncing around like mountain goats in special Basque rock climbing shoes. I was 13 when it came out. I loved it.
