Question: At the end when Tom Hanks is going over the map and the woman drives up, where exactly is the crossroads location?
Answer: Somewhere in the Great Plains, you heard the Woman's vague directions, "Whole lotta nothing 'till you get to Canada", and from the looks of things, it's not important anyway, the generic nature seems to be a plot device.
Question: Why did Chuck and Kelly not get back together at the end? Yes I know she's with that other guy but they still have feelings for each other. She didn't move on by choice, she had to move on because she thought he was dead.
Answer: She hadn't seen Chuck in years, she's married to another man, and had a child with him. Just because she still cares for Chuck (and maybe wishes things had turned out differently), doesn't mean she doesn't love her husband or wants to leave him.
And if I recall, they didn't meet because the new husband told her that Chuck didn't want to see her.
Chuck and Kelly didn't reunite at the FedEx hub because Kelly was too overwhelmed emotionally. The man she truly loved is lost to her, and she knows she cannot hurt her current husband by tearing their family apart for her own desires.
Answer: Jack and Kelly were going to be engaged around New years. So no commitment yet, whereas she was married and had a daughter with new relationship.
That would be Chuck and Kelly, not "Jack."
Question: Why doesn't Chuck just leave from the other side of the island?
Answer: Probably a variety of reasons. He could not have dragged the heavy raft to the island's other side. Even if he could, it's unlikely there was a flat clear path to get there. There may not have been an accessible beach on that side where he could launch from or that was suitable for establishing a new camp where he could build the raft.
Question: Why did Chuck stand up and then spend ages looking at the part of the toilet that had washed up?
Answer: By that time, Chuck had been on the island for four years and was becoming somewhat mentally unstable. When he first sees the toilet wall section washed up against the rocks, he approaches defensively, spear in hand, as if it's something dangerous. He seems to snap back to reality and gradually surmises it is not only benign, but potentially useful. His mind then begins working out he can adapt it as a sail to escape the island.
Answer: He couldn't believe it, of all the things to wash ashore it was a toilet. So far everything else he found could be used in a certain way, but a toilet. I didn't see the movie at the theaters but I bet the audiences were roaring with laughter.
I saw it in the theater and no-one laughed...it wasn't funny. Chuck is seeing the first man-made object he's seen in years, and he's stunned...and maybe he's getting the idea of using it as a sail.
It wasn't the actual toilet. It was just the partial wall section of the plastic enclosure for an outdoor portable toilet.
Question: How many times does Chuck get injured while stranded on the island?
Answer: 4.
Answer: The credits mention Canadian, TX. Canadian is on Hwy 83 in the Texas panhandle. The directions given mention Hwy 83 south and I-40 east. I-40 is roughly 30 miles or so south of Canadian on 83. Texas road signs are visible at the intersection. The ranch, a bed and breakfast and museum are at 9760 County Road 5, Canadian, TX. It looks like the crossroads was actually filmed maybe eight or ten miles south at the intersection of Z and 5.
