The Lake from the Future
There’s a scene where Rose contemplates suicide by jumping off of the Titanic. Before she can do so, Jack comes in, asking her whether she’s been to Wisconsin. He proceeds to explain that Wisconsin has the coldest winters (not true!) and that he’d go ice fishing with his dad on Lake Wissota? So, what’s wrong with that?
Did you know Jack was a time traveler? At the time the Titanic sank in 1912, Lake Wissota hadn’t even formed yet. It took another six years and constructing a dam in the Chippewa River before the lake came to be. Ice fishing on a lake from the future? Not likely!
