Movie legend Robert Duvall has discovered he married into a family of great Argentine aviators, but has no plans of joining them in the skies. The GODFATHER star, who is married to his fourth wife, actress Luciana Pedraza, has only recently discovered her relatives are flying fanatics - and he's fascinated. He explains, "The grandmother's the first licensed pilot and the grandfather flew the president before (JUAN) PERON. (They're an) interesting family." But Duvall won't be tempted to follow the family's love for heights even though his father keeps inviting the actor to go hang-gliding with him. Duvall adds, "He jumps off the Andes (mountain range) and hang-glides with the condor, the biggest bird in the world. He's trying to get me (to do that), but I won't do it."
