"Well, I’m not going to share the story with you because that doesn’t seem like a good idea. But we’ll see new developments in his life, his relationship. We’ll see part of his history resolved."
Very coy. Harrison Ford isn’t one to spill the beans and he’s not doing it this time around for Indiana Jones 5 either. He doesn’t want to spoil the story, but he does drop a couple hints here. The 77-year-old Star Wars actor mentions development in his “relationship” and references some part of his past being resolved.
