A Different Person, Perhaps?
Nobody really pays attention to background characters, especially when there’s a closeup of a former sexiest man in Hollywood on screen. Perhaps people were so bored of watching Titanic for the umpteenth time that they started paying closer attention to the guys in the back. And, to be frank, we’re glad they did.
We can see a pretty ridiculous mistake caused by shot splicing. While Jack and Rose and speaking, we see a man walking by with a long black coat. In the next shot, we see what’s supposed to be the same man but in a shorter tan coat. Did the second guy push the first off of the boat’s edge?!
