It must be bloody frustrating for studios trying to keep movie spoilers under wraps while journalists and fans pick apart every trailer, casting announcement and set photo looking for the slightest clue. Scripts have to be watermarked, sets have to be locked down and press releases have to be very carefully worded to maintain the element of surprise. Some directors like Christopher Nolan and J.J. Abrams have become famous for keeping such a tight grip on their stories that even the cast arent sure how it all plays out, and even those measures cant guarantee key details wont escape. While its near impossible to keep every secret hidden, the worst thing that can happen is when spoilers leak out in completely unexpected ways. Maybe an actor lets something slip out during an interview, or a piece of merchandise released months in advance will confirm key plot details. Studios have been extra careful to make sure this doesnt happen often, but even a small oversight can bring the whole thing crashing down. Collected here are some of the most bizarre ways a film has found itself spoiled; which probably resulted in some poor executive losing their job for not combing through the fine details.
