"Making a movie is difficult under the best of circumstances. Under the worst of circumstances, it's a full-fledged ordeal. As budgets grow and studios increasingly seek to satisfy the demands of franchise fans, reshoots have become commonplace. If a test audience reacts negatively to something, or the filmmakers feel they didn't hit the nail right on the head, going back for additional filming is a necessary solution. The following movies are worst-case scenario examples of that. In each case, production had to stop right in the middle so that some kind of significant problem could be fixed. Stories that weren't working, actors getting sick or even dying, and financial issues are just a few of the factors that caused these films to pause for a period of time and then restart. A few of them couldn't recover, leading to poor reputations. Amazingly, however, a few went on to become critical and/or box office hits, despite the massive behind-the-scenes woes." - ranker.com
