Name two films that are seemingly unrelated but could pass as sequel/prequel to each other with brief explanation

Just curious about your thoughts on this! Kind of a fun game to play with friends. For example one friend suggested French Connection as a prequel to Jaws where Roy Scheider moves to Amity and changes his name becoming a Chief.Another mentioned that John Wick could be connection to the matrix. Except it’s a version where Neo took the other pill. And doesn’t know he is the one. via /r/movies https://ift.tt/2IjhEvy
