The Lord of the Apes goes ape for Bo Derek.He: Tarzan. She: Maureen O'Sullivan, Enid Markey, Brenda Joyce, Andie MacDowell, Jane March and others. But of all the actresses playing opposite the screen's many Tarzans, perhaps the most famously erotic was Bo Derek.The star who was a 10 with Dudley Moore rates several tree notches higher in the reckoning of the Ape Man. he defends her against a beachcombing King of the Beasts, untangles her from a python's squeeze and takes on kidnapping primitives who have covered her with white body paint. The Englishwoman who comes to West Africa to find her father (Richard Harris) obviously finds more and l'amour. Romance is part of the adventure when Tarzan (Miles O'Keeffe) is the jungle beau and Bo's thejungle Jane.
