Found that over at SlashFilm. They also had the following description from USA Today.
When last we saw Indy, he was riding off into the sunset in 1989â€™s The Last Crusade, set in 1938 near the start of World War II. The new movie, due this spring, is set at the height of the Cold War in 1957, so the character has aged in real time â€” 19 years.
â€œHeâ€™s teaching and having kind of a quiet life,â€ the producer says. Once the archaeologist is thrust back into danger, the signature Indiana Jones red line tracing across the map will take him to New Mexico, Connecticut, Mexico City and the jungles of Peru.
The Nazis are no longer Indyâ€™s chief foe â€” heâ€™s racing for the Crystal Skull against operatives from the Soviet Union, including Oscar winner Cate Blanchett as the seductive Agent Spalko. â€œIndy always has a love-hate relationship with every woman he ever comes in contact with,â€ Marshall says.
The artifact of the title is inspired by real quartz sculptures of disputed origins that are carved in a way that defies the natural structure of the crystal.
â€œThe theory is they are shaped by higher powers or alien powers or came from another world, or an ancient Mayan civilization had the powers,â€ Marshall says.
I’m trying not to get my hopes up too much for this film. It hold a special memory for me, much like Star Wars. We all know the Star Wars prequels were disappointing (different levels for different people).
Everything about Indiana Jones and the Kingdom of the Crystal Skull points to the same thing. Multiple scripts, George Lucas, Indy has a son. However, that poster just makes it all go away, at least for a moment.
