The Bell thing is part of the plot of the new Jones movie, if it's still there after the major rewrites... But even that feels like a conspiracy... Consider Spielberg role in this phenomena. It's almost like he has inside information, cause all of his movie tie in. Indiana Jones 4 was awful, but it covered UFOs. Now this 5th movie intends to bring in the bell and time travel...
And from all accounts, it's awful! So, is the last one and this one intentionally awful so no one will watch or care that they're also getting a smidgeon of real history? Wouldn't that be fun if this wasn't far fetched?
