Production on Indiana Jones 5 continues to be well-stalked, probably owing to the fact that the location shooting has happened to take place in some fairly public places so far.
It would be exceptionally difficult to hide what the production is doing right now. Shooting is currently taking place on a street in Glasgow that has been extensively converted into New York circa 1969:
Observers have dated the environment based on various context clues amongst the set dressing, positing that the movie will depict the Apollo 11 Ticker Tape Parade. New York is also home to a number of prestigious museums, which wouldn't be altogether radical territory for a tenured professor of archeology.
Whatever brings Indy to the Big Apple, it seems like a reasonable place to set Act I before he gets pulled into the proverbial One Last Adventure. Lao Che rises again It could be anything!
